180 = 2 x 2 x 3 x 3 x 5; 252 = 2 x 2 x 3 x 3 x 7;
Common factors: 2 x 2 x 3 x 3 ie HCF = 36
The highest common factor of the numbers 294, 252 and 210 is 42.
36
1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
The multiples of 36 (which are infinite) are all divisible by 36, including these: 36, 72, 108, 144, 180, 216, 252, 288 . . .
You multiply 126 x 2 = 252
The GCF is 36.
It is: 36
The highest common factor of 56 and 252 is 28
The GCF/HCF of 108 and 252 is 36.
The HCF is: 12
7
The GCF is 28.
If the highest common factor of 120 and 252 is 12 10*12 = 120 21*12 = 252 Then it follows that the highest common factor of CXX and CCLII is XII X*XII = CXX XXI*XII = CCLII
