The Greatest Common Factor (GCF) is: 7
The highest four digit number with 13 and 7 as common factors is 9919, which is equal to 13 x 763 and 7 x 1417.
The only proper factors of 77 are 7 and 11. 11 isn't a factor of 259 but 7 is, so the answer is 7.
Determine the prime factors of both numbers.119 = 7 x 17259 = 7 x 37The only common factor of 119 and 259 and therefore the Highest Common Factor is 7.
The factors of 105 are 3,5, & 7. The factors of 63 are 3,3, & 7. One lot of '3' and one lot of '7' is common to both numbers. Hence 3 x 7 = 21 , which is the HCF of 105,& 63.
1 and 7
7
The GCF is 7.
14 has factors 1, 2, 7 and 1449 has factors 1, 7 (7x7 to be exact), and 49The highest common factor is 7
The factors of 5 are 1 and 5. The factors of 7 are 1 and 7. The factors of 10 are 1,2,5 and 10. So the highest common factor is 1.
1, 2, 7, and 14 are the factors of 14.1,2,14The factors of 14 are1,2,7,and14
the lowest is 7, but you wanted the highest. that would go on forever. * * * * * No. 7 IS the highest COMMON factor.
