Question

find the LCM and HCF of 200 and 420 by using prime factorization method​

Answer 1

Answer:

lcm (200; 420) = 23 × 3 × 52 × 7;

lcm (200; 420) = 23 × 3 × 52 × 7 = 4,200

numbers have common prime factors

Integer numbers prime factorization

And

HCF (200,420)= Find the prime factorization of 200

200 = 2 × 2 × 2 × 5 × 5

Find the prime factorization of 420

420 = 2 × 2 × 3 × 5 × 7

To find the gcf, multiply all the prime factors common to both numbers:

Therefore, GCF = 2 × 2 × 5

GCF = 20
