The Highest Common Factor is 126
The GCF is 42.
The GCF is 42.
5040 ÷ 1000 = 5 r 40 1000 ÷ 40 = 25 r 0 ⇒ hcf of 5040 and 1000 is 40.
The LCM is used with whole numbers, not decimals.
63, 126, 189, 252, 315, 378, 441, 504, 567, 630, 693, 756, 819, 882, 945, . . . forever
The LCM is: 504
The GCF/HCF of 54 and 504 is 18.
The GCF is 42.
so, 80 % of 630 = 0.8 * 630 = 504
It is: 28
the answer is 49
The GCF is 84.
The GCF is 90.
The highest common factor of the numbers 490 and 630 is 70.
LCM = product/HCF; HCF is 6 so LCM = 12 x 42 = 504
The GCF is 63.
126, 252, 378, 504, 630, 756, 882 . . .
LCM of two numbers is their product divided by their HCF. First find HCF: 462 = 2 x 3 x 7 x 11; 630 = 2 x 3 x 3 x 5 x 7. The common factors are 2 x 3 x 7 ie HCF = 42 LCM is therefore 462 x 630 / 42 ie 11 x 630 = 6930
