Answer 1

Answer:

How to find the 2 numbers when their LCM and HCF are given, Since A*B=LCM(A,B)*GCF(A,B), this means that A and B can just be the LCM and GCF, along with other answers. So if the GCF is 7 and the LCM is 35, you can For instance, take 8 and 12, the gcd of these two numbers or the HCF of two numbers will be 4.

Answer 2

Answer:

The prime factors of 16 = 2 × 2 × 2 × 2. We can express the factor tree to find the prime factors of 16 in another way also. The prime factors of 16 = 2 × 2 × 2 × 2.

Step-by-step explanation:

HCF of 42 and 77 is 7.
