What are the highest common factor and lowest common multiple of 30 36 and 42?
HCF(30, 36, 42) = 6 LCM(30, 36, 42) = 1260
What is the difference between the LCM and HCM of 42 nd 84?
Whenever one of the numbers is a multiple of the other, the larger number is the LCM and the smaller number is the GCF. In this case, the difference between them is 42. The highest common multiple of any set of integers is infinite.
What is the LCM of 462 and 630?
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
