The GCF of 24 and 72 is 24First find all the prime factors for each number.24: 2 x 2 x 2 x 372: 2 x 2 x 2 x 3 x 3Next find all the prime factors common to both numbers in this case it will be the following:GCF: 2 x 2 x 2 x 3 = 24Factors of 24 include 1,2,3,4,6,8,12,24Factors of 72 include 1,2,3,4,6,8,9,12,18,24,36,72Therefore the greatest common factor of 24 and 72 is 24.Since 24 is a factor of 72, it is automatically the GCF.
To find the greatest common factor (GCF) of 24, 63, and 72, we first need to find the factors of each number. The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24. The factors of 63 are 1, 3, 7, 9, 21, and 63. The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. The GCF of 24, 63, and 72 is the largest number that is a factor of all three numbers, which is 3.
The Greatest Common Factor of 16, 48, 72: 8
I assume that's supposed to be a fraction, 24/72. The idea is to find a common factor - a number that is a factor of both 24 and 72. Then, divide both numbers by this factor. Repeat, until you find no more common factors.
Factors of 72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
