To find the Highest Common Factor using the cross division method is as follows:
180/2 is a factor of 180, 180 divided by 2 is 90
90/2 is a factor of 90, 90 divided by 2 is 45
45/3 is a factor of 45, 45 divided by 3 is 15
15/3 is a factor of 15, 15 divided by 3 is 5
5/5 is a factor of 5, 5 divided by 5 is 1
The highest Common factor is:
2 x 2 x 3 x 3 x 5 = 180
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
150/2 is a factor of 150, 150 divided by 2 is 75
75/3 is a factor of 75, 75 divided by 3 is 25
25/5 is a factor of 25, 25 divided by 5 is 5
5/5 is a factor of 5, 5 divided by 5 is 1
The highest Common Factor is:
2 x 3 x 5 x 5 = 150
