2 x 2 x 5 = 20
2*2*5=20.
To find the HCF, you first have to express both numbers as the product of their prime factors: 15 = 3x5 20 = 2x2x5 The next step is to identify any common prime factors. In this case both numbers have a 5 as a prime factor. Therefore the HCF of 15 and 20 is 5.
what number is not a prime factor
The greatest common prime factor of 10 and 20 is 5.
3 + 17 = 20
Prime factorization of 1000:= 20 * 50= (4 * 5 ) * (10 * 5)= (2 * 2* 5) * (2 * 5 * 5)= 2 * 2 * 2 * 5 * 5 * 5
To find the HCF, you first have to express both numbers as the product of their prime factors: 15 = 3x5 20 = 2x2x5 The next step is to identify any common prime factors. In this case both numbers have a 5 as a prime factor. Therefore the HCF of 15 and 20 is 5.
No, 20 isn't prime.
what number is not a prime factor
4 is a prime factor of 20 whereas it isn't a factor of 50.
5 is the greatest prime factor of 20.
The prime factors of 20 are: 2 and 5.
No, 5 is.
5 is a prime factor of both numbers.
The greatest common prime factor of 10 and 20 is 5.
3 + 17 = 20
20 10,2 5,2,2
yes you do because 5 is a factor of 20 and so is 2 and 5x2=10 and 10 is a factor of 20
