Greatest Common Factor
The difference between the two numbers, 77 - 63, is 14. It they have a greatest common factor other than 1, it is 14 or a factor of 14, such as 2 or 7. The numbers are not divisible by 14, but they are divisible by 7, so the greatest common factor is 7.
Another way to determine the greatest common factor is to find all the factors of the numbers and compare them.
The factors of 63 are 1, 3, 7, 9, 21, and 63.
The factors of 77 are 1, 7, 11, and 77.
The common factors are 1 and 7. Therefore, the greatest common factor is 7.
The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.
The prime factors of 63 are 3, 3, and 7.
The prime factors of 77 are 7 and 11.
The prime factors in common are a single 7, so the greatest common factor is 7.
Least Common Multiple
The least common multiple of two numbers is their product divided by their greatest common factor: 63 x 77 ÷ 7 = 693.
