To find the greatest common factor (GCF) of two numbers, you need to determine the largest number that divides evenly into both numbers. To find the GCF of 315 and 693, you can start by finding the prime factors of each number. The prime factors of 315 are 3, 3, 5, 7, and the prime factors of 693 are 3, 3, 7, 11. The GCF is the product of the common prime factors raised to the lowest power, which in this case is 3 * 3 * 7 = 63. Therefore, the greatest common factor of 315 and 693 is 63.

What is the greatest common factor of 231 and 693?

The greatest common factor (GCF) of two numbers is the largest positive integer that divides both numbers without leaving a remainder. To find the GCF of 231 and 693, you can use prime factorization. The prime factorization of 231 is 3 x 7 x 11, and the prime factorization of 693 is 3 x 3 x 7 x 11. The common factors are 3, 7, and 11, so the GCF of 231 and 693 is 3 x 7 x 11, which equals 231.

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.
