Question

How do I find the GCF of three numbers using long division method??

Answer 1

Lets take example as - 64, 24, 16

now

2 | 64  24  16

2 | 32  12  08

2 | 16  06  04

2 | 08  03  02

2 | 04  03  00

2 | 02  03  00

3 | 00  03  00

  | 00  00  00

  So, GCF = 2*2*2*2*2*2*3

= 192 (It means all the three numbers are having a multiple as 192)

To find GCF, we just have to divide the three numbers in this manner together from the smallest number.
