As a product of its prime factors: 3*5*7*11 = 1155
As a product of its prime factors: 3*5*7*11 = 1155
1155 385,3 77,5,3 11,7,5,3 3 x 5 x 7 x 11 = 1155
As a product of its prime factors: 3*5*7*11 = 1155. From the given information its factors can be worked out and that 1 and 1155 are also factors
The greatest common factor of 630 , 1155 = 105
1, 3, 5, 7, 11, 15, 21, 33, 35, 55, 77, 105, 165, 231, 385, 1155
It is: 165
The GCF is: 165
Ascertain the prime factors of both numbers :- 660 = 2 x 2 x 3 x 5 x 11 1155 = 3 x 5 x 7 x 11 The only factors (other than 1) that both numbers have in common are 3, 5 and 11. The greatest common factor is therefore 3 x 5 x 11 = 165 165 is the GCF of 660 and 1155
16.5*2=33
The factors of 1155 = 1, 3, 5, 7, 11, 15, 21, 33, 35, 55, 77, 105, 165, 231, 385, and 1155. The prime factors of 1155 are 3, 5, 7, 11.
Common factors of 2850 and 1155 are: 1, 3, 5, and 15.
