Factors of 40: 1,2,4,5,8,10,20,40 1 x 40 2 x 20 4 x 10 5 x 8 Factors of 30: 1,2,3,5,6,10,15,30 1 x 30 2 x 15 3 x 10 5 x 6 Common factors: 1, 2 5, 10 10 is the highest common factor.
The factors of 32 are 1, 2, 4, 8, 16, and 32The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40
The factors of 40 are 1,2,4,5,8,10,20 and 40. For them to be common, they need to be compared to another set of factors.
The common factors of 30 and 40 are 1, 2, 5, 10
To find the GCF of 3 numbers you first need to write them as their prime factors: 32 = 2x2x2x2x2 40 = 2x2x2x5 64 = 2x2x2x2x2x2 The next step is to identify any common factors. In this case, all three numbers have three 2s as prime factors. Multiply these together to find the GCF: 2x2x2 = 8 Thus the GCF of 32, 40 and 64 is 8.
The highest common factor of 32 and 40 is 8.
The highest common factor of 25 and 40 is 5.
The GCF of 32 and 40 is 8.The factors of 32 are 1, 2, 4, 8, 16, and 32.The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40.The common factors are 1, 2, 4, and 8, so the greatest common factor is 8.You can also determine the greatest common factor from the prime factors.The prime factors of 32 are 2, 2, 2, 2, and 2.The prime factors of 40 are 2, 2, 2, and 5.The prime factors they have in common are 2, 2, and 2, so the greatest common factor is 2 x 2 x 2 = 8.It is: 8The GCF is 8.
