We want the GCF or highest common factor of 15 and 24. The factors of 15 and 1,3, and 5.For 24 we have 1,3, 8, 12 and 24.Since 5 is not a factor of 24, the GCF or highest factor is 3

The greatest factor of 24 is 24. The greatest factor of a number is the number itself.

The GCF is 3.

Eight is the largest common factor of 24 and 8

The first multiple ... ' 8 ' ... is the only factor of both 24 and 32 that's a multiple of 8 .

Either or both. 12 is a factor of 24. 12 is a multiple of 6. 12 is both a factor and a multiple of itself.

The greatest common factor is the highest number that is a factor of both numbers (divides into them evenly). 24/24 = 1, and 48/24 = 2, so it's 24. 24 goes evenly into both numbers, and is definitely the greatest because it is the highest factor of 24.

The greatest number by which both 24 and 9 are divisible is 3. Therefore, greatest common factor is 3.Alternate method:P.F. of 9 = 3x3P.F. of 24 = 2x2x2x33 is the only prime number which is the factor of both 24 and 9.Therefore, GCF = 3.

The ratio is simply 24/15. That fraction (or ratio) can be simplified by dividing both numbers by their highest common factor.
