To find the Greatest Common Factor (GCF) of 20, 30, and 90, you first need to factor each number into its prime factors. The prime factorization of 20 is 2^2 * 5, of 30 is 2 * 3 * 5, and of 90 is 2 * 3^2 * 5. Then, you identify the common prime factors among the numbers, which are 2 and 5. Finally, you multiply these common prime factors together to find the GCF, which is 2 * 5 = 10.
gcf(20, 30, 90) = 10
30The gcf is 30
The GCF is 30.
Prime factorization of 32 = 2x2x2x2x2 Prime factorization of 90 = 2x3x3x5 Prime factorization of 30 = 2x3x5 What is common in the prime factorization of the numbers? Only 2 is common, so GCF is 2.
The GCF is 3.
gcf(20, 30, 90) = 10
The GCF is 10.
The GCF of 30 and 90 is 30.
30The gcf is 30
GCF(210, 90) = 30.
The GCF is 30.
The GCF of 90 and 120 is 30. The factors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90. The factors of 120 are 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, and 120. The GCF of 90 and 120 is 30.
The GCF for 20 40 90 is 10.
The GCF is 2.
The GCF is 10.
The GCF is 15.
The greatest common factor (GCF) of 15, 30, 90 is 15.
