The factors of 51 are 3 and 17. The factors of 11 are 3 and 37. Therefore, the highest common factor is 3.
The highest common factor is 3
GCF of 21 and 51 is 3.21=3*751=3*17
They are 1 and 3
The greatest number which divides both 51 and 85 is 17. So, greatest common factor is 17.Alternate method:P.F. of 51 = 3x17P.F. of 85 = 5x17Clearly, from the P.F. of both numbers 17 is the greatest common factor.The GCF is 17.51 and 85's highest common factor is 17.
The factors of 51 are 3 and 17. The factors of 11 are 3 and 37. Therefore, the highest common factor is 3.
The GCF is 3.
The highest common factor is 3
The GCF is 3.
51
51 and 18's highest common factor is three.
51 = 1 x 3 x 17; 221 = 1 x 13 x 17. GCF is 1 x 17 = 17.
The GCF is 1.
The GCF is 3.
51 is.
The common factors are: 1, 3, 17, 51
the greatest common factor of 51 and 34 is 17 because 17 is a factor of both 51 and 34 and it happens to be the greatest.
