The GCF is 5.
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 GCF is 15.
greatest common factor of 45 and 35 is 5.Five (7*5 , 9*5)
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 Highest Common Factor is: 9
15
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.
The GCF is 5.
