Factors of a number are positive integers which that original number can evenly divide by. We are trying to find factors of 661.5, but if we divide this number by any integer, it will result in a decimal or fraction. This is because it is not an integer itself. Thus, there aren't any factors of 661.5.
1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
61 is prime. Its only factors are 1 and itself.
For 654 and 66 the common factors are 1, 2, 3, 6.
Factors of 72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72.Factors of 660: 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660.GCF (72, 660) = 12
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
42 - The prime factors are: 2, 3 and 7660 - The prime factors are: 2, 3, 5 and 11
660 feet = 0.125 miles
The prime factors of 660 are 2 x 2 x 3 x 5 x 11.
The common factors of 660 and 770 are: 1, 2, 5, 10, 11, 22, 55, and 110
Itself and any of its factors
The number 660 is composite because it has more than 2 factors.
As a product of its prime factors it is: 2*2*3*5*11 = 660 or as 22*3*5*11 = 660
The factors of 660 are: 1 2 3 4 5 6 10 11 12 15 20 22 30 33 44 55 60 66 110 132 165 220 330 660The prime factors of 660 are: 2, 3, 5, 11
The factors of 660 are 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, and 660.
Any multiple of 660.
The first step is to express these numbers as products of their prime factors: 315 = 3x3x5x7 660 = 2x2x3x5x11 The next step is to identify any common prime factors. In this case the common prime factors are 3 and 5. Multiply these and you get: 3x5 = 15 Thus the HCF of 315 and 660 is 15.
Any of its factors including itself
The least common factor of 12,15, and 22 is one, because it has no other common factors.
The factors of 660 are 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660. For them to be common, they need to be compared to another set of factors. If that's 6 and 60, the common factors are 1, 2, 3 and 6.
