What is the greatest common factor 15 and 25?
Prime Factors of 15 are 3 and 5 Prime Factors of 25 are 5 and 5 Obviously 5 is the GCF, however, in general find the prime factors and multiply all the common factors. The GCF is 5.
What is the greatest common factor of 15 and 75?
Since 15 is a factor of 75, and 15 is its own largest factor, the greatest common factor must be 15.Another way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 15 are 1, 3, 5, and 15.The factors of 75 are 1, 3, 5, 15, 25, and 75.The common factors are 1, 3, 5, and 15. Therefore, the greatest common factor is 15.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 15 are 3 and 5.The prime factors of 75 are 3, 5, and 5.The prime factors in common are 3 and 5, so the greatest common factor is 3 x 5 = 15.It is 15
