What is the greatest common factor of 16 and 63?

Since 16 is 24, its only factors other than 1 are multiples of 2, which means that because 63 is not an even number, the greatest common factor is 1. Another way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 16 are 1, 2, 4, 8, and 16. The factors of 63 are 1, 3, 7, 9, 21, and 63. The only common factor is 1. Therefore, the greatest common factor is 1. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 16 are 2, 2, 2, and 2. The prime factors of 63 are 3, 3, and 7. There are no prime factors in common, which means the numbers are relatively prime, so the greatest common factor is 1.


What is greatest common factor and least common multiple of 63 and 77?

Greatest Common FactorThe 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 MultipleThe least common multiple of two numbers is their product divided by their greatest common factor: 63 x 77 ÷ 7 = 693.
