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
Its only prime factor is 5 and as a product of its prime factors: 5*5 = 25
There are no common prime factors!
Factors of 5 are 1 and 5 Factors of 25 are 1, 5 and 25 Prime factor of both numbers is 5
