The GCF is 39.
21
Prime factorization:102 = 2 x 3 x 17663 = 3 x 13 x 17The GCF of 102 and 663 is 3 x 17 = 51.
Highest common factor of 273 and 315 is 21.
The first step in finding the greatest common factor is to break the numbers down into their prime factors: 663=3x13x17 1547=7x13x17 The next step is to identify any common factors. In this case, the common prime factors are 13 and 17. To find the greatest common factor we multiply these together: 13x17=221 So 221 is the GCF of 663 and 1547.
The GCF is 39.
The GCF of 78 and 663 is: 39
The GCF/HCF of 182 and 273 is 91.
The GCF is: 91
The GCF is 1.
The GCF of 42 and 273 is 21. 42 = 2 x 21 273 = 13 x 21
21
It is: 3
Prime factorization:102 = 2 x 3 x 17663 = 3 x 13 x 17The GCF of 102 and 663 is 3 x 17 = 51.
Prime factorization of: 195= 3 x 5 x 13 273= 3 x .....13 x 7 =============== GCF=3 x .....13 GCF=39
The GCF is 39.
Highest common factor of 273 and 315 is 21.
