Question

find the HCF of 252 and 144 with the prime factorization method​

Answer 1

the numbrs given are 252 and 144

we have to find hcf using prime factorisation method

when we  primefactorize the  252 then

252= 2*2*3*3*7 and

144 = 2*2*2*2*3*3

in both we find the common 2 ,2,3,3

so we multiply 2*2*3*3* = 36

so the hcf is 36
