20 is the correct Answer To all brothers who are confused right now Suppose we need to find the factors of 540 (2²×3³×5¹) which are divisible by 6 but not by 27 The factors which are divisible by 6 are (6,12,18,30,36,54,60,90,108,180,270,540) but out of these 12 only 4 factors are divisible by 27 i.e(54,108,270,540) Total divisible by 6 =12 And out of these 12 , 4 factors are also divisible by 27 so , 12-4=8 (answer) Or 2¹×3¹(2¹×3¹×5¹) 2×2×2= 8 answer We can't take 3³ but we can go upto 3² Similarly In homework question we can't take 3⁶ but can go upto 3⁵ 2⁴×3²(3³×5⁴) 4×5=20 (answer) 3²×3³=3⁵
N = 729 × 5^4 × 3^7 × 2^4 = 5^4 × 3^13 × 2^4 = 3^2 × 2^4 ( 5 ^4× 3^11) Now 729 = 3^6 and to make it we need to multiply with minimum 3^4 Now, N = 3^2 × (3^4) × 3^4) × 2^4 [( 5^4 × 3^3) ] And from this 5^4 × 3^3 we can't get 3^4 . so we stop here. The answer becomes (4+1)(3+1) = 20
144= 2⁴x3² and 729= 9³= 3⁶ Now, 2⁴x3²) 3⁵x5⁴x3⁶. Here, we need to eliminate multiples of 3 because 729 is divisible by 3. Therefore the ans is: 4+1 = 5
@@akashpilaniya5389 sare case me Prime number ko hi eliminate kara jata hai. Uska power matter nahi karta. Idhar prime number 3 hai. To jaha kahi 3 dikhe eliminate kar do uska power kitni bhi ho. Sorry for my bad Hindi
@@dharmendrakumar4973 No. Why are you considering 9³ ? 9 is not a prime number. We have to take Only prime numbers and their powers. It's called prime factorisation.

20 is the correct Answer
To all brothers who are confused right now
Suppose we need to find the factors of 540 (2²×3³×5¹) which are divisible by 6 but not by 27
The factors which are divisible by 6 are (6,12,18,30,36,54,60,90,108,180,270,540) but out of these 12 only 4 factors are divisible by 27 i.e(54,108,270,540)
Total divisible by 6 =12
And out of these 12 , 4 factors are also divisible by 27 so , 12-4=8 (answer)
Or
2¹×3¹(2¹×3¹×5¹)
2×2×2= 8 answer
We can't take 3³ but we can go upto 3²
Similarly
In homework question we can't take 3⁶ but can go upto 3⁵
2⁴×3²(3³×5⁴)
4×5=20 (answer)
3²×3³=3⁵
Yes
Yup
Thankyou
@@crazymaths7683 Glad to know that it helped.
N = 729 × 5^4 × 3^7 × 2^4
= 5^4 × 3^13 × 2^4
= 3^2 × 2^4 ( 5 ^4× 3^11)
Now 729 = 3^6 and to make it we need to multiply with minimum 3^4
Now, N = 3^2 × (3^4) × 3^4) × 2^4 [( 5^4 × 3^3) ]
And from this 5^4 × 3^3 we can't get 3^4 . so we stop here.
The answer becomes (4+1)(3+1) = 20
Good bhai mera b yhi ans tha kuchh log 5 nikale baithe h
Haan wo galat bata raha hain.
Ans to 20 hi hoga
3 ki power 3 chod diye londe sare raata maar rhe h and 20 hoga kyuki jitne bhi example kre the unme direct multiple bn ra tha
Answer 5
badhiyaa samjhaye ho guru
144= 2⁴x3² and 729= 9³= 3⁶
Now, 2⁴x3²) 3⁵x5⁴x3⁶. Here, we need to eliminate multiples of 3 because 729 is divisible by 3. Therefore the ans is: 4+1 = 5
Sare factor ku eliminate kra 3 ka 3 ki power 6 tk kr skte the??

Don’t wry keep revising
Last wala ka smjh ni aa rha concept..
144(3^3 × 5^4) hona chahiye, ye divisible bhi nahi h 729 se. Calculator se check kar liya
