The GCF is 5.
The greatest common factor of 45 and 320 is 5.
Use the following factor trees to determine the answer355, 7and637, 97, 3, 37 is the common factor of 35 and 63
The GCF of 20, 35 and 45 is 5.
39 and 45's highest common factor is three.
It is: 5
55
The GCF is 5.
7 * 5 = 359 * 5 = 45The highest common factor is 5.
The greatest common factor of 45 and 320 is 5.
The Highest Common Factor is: 9
greatest common factor of 45 and 35 is 5.Five (7*5 , 9*5)
The GCF is 5.
The greatest common factor of 45 and 150 is 15.
1 is their highest common factor.
The GCF of 45 and 80 is 5. Prime factors: 45 = 5x3x3 80 = 5x2x2x2x2 the only prime factor in both is 5, and so the highest common factor is 5. Alternative method: 80 mod 45 = 35 45 mod 35 = 10 35 mod 10 = 5 10 mod 5 = 0 so HCF = 5.
The GCF is 5.
That would be 15. Only a number ending in five would be a factor of 75. 45 is not. 35 is not. 25 is not. 15 is, and it also is a factor of 90. This makes it the highest common factor of 75 and 90, although it is not a prime factor.
