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.
1,2,3,4,5,6,10,11,12,15,20,22,30,33,44,55,60,66,110,132,165,220,330,660 1,3,5,7,11,15,21,33,35,55,77,105,165,231,385,1155 Common set: 1,3,5,11,33,55,165
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 prime factors of 660 are 2 x 2 x 3 x 5 x 11.
The factors of 308 are: 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308 The factors of 616 are: 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616 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 The common factors are: 1, 2, 4, 11, 22, 44 The Greatest Common Factor: GCF = 44
Least Common Multiple (LCM) for 12 10 11 is 660
The common factors of 660 and 770 are: 1, 2, 5, 10, 11, 22, 55, and 110
1,2,3,4,5,6,10,11,12,15,20,22,30,33,44,55,60,66,110,132,165,220,330,660 1,3,5,7,11,15,21,33,35,55,77,105,165,231,385,1155 Common set: 1,3,5,11,33,55,165
The least common factor of 12,15, and 22 is one, because it has no other common factors.
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 prime factors of 660 are 2 x 2 x 3 x 5 x 11.
For 654 and 66 the common factors are 1, 2, 3, 6.
660
The factors of 49 are: 1, 7, 49The 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 common factors are: 1The Greatest Common Factor (GCF) is: 1
Since 220 is a factor of 660, it is automatically the GCF.
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
Itself and any of its factors
The least common multiple of the numbers 5, 12 and 11 is 660.
