Find the HCF for these sets of numbers 30, 210 and 700?

Answer 1

To find the highest common factor (HCF) of 30, 210, and 700, you can use the prime factorization method.

Prime Factorization:

Prime factorize each number:

30 = 2 * 3 * 5

210 = 2 * 3 * 5 * 7

700 = 2^2 * 5^2 * 7

Identify Common Prime Factors:

Identify the common prime factors among the numbers: 2, 3, 5, and 7.

Multiply Common Prime Factors:

Multiply the common prime factors: 2 * 3 * 5 * 7 = 210

Therefore, the HCF of 30, 210, and 700 is 210.
