The prime factors of 660 are 2 x 2 x 3 x 5 x 11.
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.
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
22 x 3 x 5 x 11 = 660
2 x 2 x 3 x 5 x 11 = 660
factors: 1, 2, 3, 4, 5, 6, 8, 10, 11, 12, 15, 20, 22, 24, 30, 33, 40, 44, 55, 60, 66, 88, 110, 120, 132, 165, 220, 264, 330, 440, 660 prime factors: 2(3), 3, 5, 11
Its prime factors are: 2, 3, 5 and 11

The number 660 is composite because it has more than 2 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 660The prime factors of 660 are: 2, 3, 5, 11
As a product of its prime factors it is: 2*2*3*5*11 = 660 or as 22*3*5*11 = 660
42 - The prime factors are: 2, 3 and 7660 - The prime factors are: 2, 3, 5 and 11
For 33: 3 and 11 For 660: 2, 3, 5 and 11
Prime factors of 144 are: 2^4 and 3^2 Prime factors of 660 are: 2^2, 3, 5 and 11 Multiply the highest primes from both numbers: 2^4x3^2x5x11 = 7920 => LCM
You divide by prime numbers until you get to 1, and then the numbers you divided by are the prime factors. eg: 660 It's even so I divide by 2 and get 330 That's even so I divide by 2 and get 165 That ends in 5 so I divide by 5 and get 33 I know that divides by 11 so I divide it by 11 and get 3 Divide that by 3 and get 1. I divided by 2,2,5,11 and 3, so those are the prime factors of 660.
Prime factors of 12 are 22 and 3 Prime factors of 15 are 3 and 5 Prime factors of 22 are 2 and 11 Least common multiple = 22*3*5*11 = 660
The common factors of 660 and 770 are: 1, 2, 5, 10, 11, 22, 55, and 110
22 x 3 x 5 x 11 = 660
