What is the hcf of 432 and 240

Note: x*y means x times y, not x^y

hcf aka gcf meaning greatest common factor

ex

20 and 12

we know that they have a factor of 4 and that is the highest

to find teh gcf of any 2 numbers we find the factors first and group the common ones to make the greatest common factor

so we have 432 and 240

432=2*2*2*2*3*3*3

240=2*2*2*2*3*5

we group the common ones

we notice that there is a group of (2*2*2*2*3) in both as shown bolded below

432=2*2*2*2*3*3*3

240=2*2*2*2*3*5

so we have 2*2*2*2*3

we multiply

2*2*2*2*3=4*4*3=16*3=48

GCF or HCF of 432 and 240 is 48
