Question

find the HCF of the following by prime factorisation METHOD:problem 216,530?

Answer 1

$216 = 2 \times 108 \\ \: \: \: \: \: \: \: \: = 2 \times 2 \times 54 \\ \: \: \: \: \: \: \: \: = 2 \times 2 \times 2 \times 27 \\ \: \: \: \: \: \: \: \: = 2 \times 2 \times 2 \times 3 \times 9 \\ \: \: \: \: \: \: \: \: = 2 \times 2 \times 2 \times 3 \times 3 \times 3 \\ 530 = 2 \times 265 \\ \: \: \: \: \: \: \: \: \: = 2 \times 5 \times 53 \\ the \: common \: factor \: of \: both \: that \: is \: 216 \: and \: 530 \: is \: 2 \\ the \: hcf \: is \: 2$
