Question

find the HCF of 58 and 70 by prime factorisation method​

Answer 1

Answer:

See attachment of long division method

Step-by-step explanation: See we divide the bigger number by the smaller. Then we take the last divisor and make it the dividend. And the remainder of the last division we did becomes the divisor. We continue this process until the remainder becomes 0. When it does, the divisor of our last division, in this case,2 becomes our HCF.

$58 = 2 \times 29 \\ 70 = 2 \times 5 \times 7$

$HCF \: is = 2$
