It is: 5
21 and 80's highest common factor is one.
The GCF is 8.
The Greatest Common Factor (GCF) is: 40
8 9*8 = 72 10*8 = 80
It is: 5
The highest common factor of the numbers 32, 80 and 160 is 16.
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.
21 and 80's highest common factor is one.
Since 8 is a factor of 80, it is automatically the GCF.
