The factors of 20 are 1, 2, 4, 5, 10, and 20.The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30.The factors of 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40, 80The gcf of 20, 30, and 80 is 10.
2 x 3 = 6 2 x 5 = 10 The GCF is 2.
the GCF of 9 & 30 = 3 Prime Factorization of: 9 = 3 * 3 30=.....3 * 2 * 5 =========== GCF = 3
The factors of 10 are:1, 2, 5, 10The factors of 30 are:1, 2, 3, 5, 6, 10, 15, 30The factors of 40 are:1, 2, 4, 5, 8, 10, 20, 40The common factors are:1, 2, 5, 10The Greatest Common Factor (GCF) is:10
GCF of 30 & 100 = 10prime factorization of:30 = 2 x 5 x 3100=2 x 5 ----x 5 x 2==============GCF=2 x5GCF=10
It is 10.Think of it this way:30=3*10=3*2*5=2*3*570=7*10=7*2*5=2*5*7What they both have in common is 2 and 5.2*5= 10
GCF(10, 25, 30) = 5.
The factors of 10 are:1, 2, 5, 10The factors of 30 are:1, 2, 3, 5, 6, 10, 15, 30The common factors are:1, 2, 5, 10The Greatest Common Factor (GCF) is:10
The GCF is 5.
The systematic way to get the answer is: 90 = 2*3*3*5 210 = 2*3*5*7 So gcf is 2*3*5 = 30
The factors of 20 are 1, 2, 4, 5, 10, and 20.The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30.The factors of 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40, 80The gcf of 20, 30, and 80 is 10.
The GCF of 30 and 45 is 15.The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30.The factors of 45 are 1, 3, 5, 9, 15, and 45The GCF is 15.
2 x 3 = 6 2 x 5 = 10 The GCF is 2.
the GCF of 9 & 30 = 3 Prime Factorization of: 9 = 3 * 3 30=.....3 * 2 * 5 =========== GCF = 3
The factors of 30 are:1, 2, 3, 5, 6, 10, 15, 30The factors of 140 are:1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140The common factors are:1, 2, 5, 10The Greatest Common Factor (GCF) is:10
30 2 x 15 = 30 3 x 10 = 30 5 x 6 = 30
The GCF is 10.
