18, 36, 54, 72, 90, 108, 126, 144, 162, 180, 198, . . .
The HCF of 4 and 90 is 2.
The HCF of the numbers 540 and 108 is 108.
The GCF is 18.
They are 18, 36, 54, 72, 90, 108, 126, 144 and 162.
The GCF is 6.
Here are the first 10: 18, 36, 54, 72, 90, 108, 126, 144, 162, 180 . . .
The GCF is 21.
The GCF is 14.
If there is a remainder of 2 then number will divide 2 less than 110 (= 108) and 128 (=126) and be the largest such number. Thus need the hcf of 108 and 126: 108 = 22 x 33 126 = 2 x 32 x 7 hcf = 2 x 32 = 18 Thus 18 is the greatest number which will divide 110 and 128 with a remainder of 2 in each case.
18, 36, 54, 72, 90, 108, 126, 144
The LCM of 126 and 108 is 756.
