"Common" means "same for both". There's no such thing as 'common' factors of a
single number. In order to have anything common, you need at least two of them.
Common factors are factors that are common to two or more numbers. For example, 7 is a factor of 14, 49, and 35, therefore it is a common factor of those three numbers. 2, 4, and 17 are all factors of 136, and 3, 5, and 17 are all factors of 255, so 17 is a common factor of 136 and 255.
GCF means Greatest Common Factor. GCF of 51 and 255 will be, = 255/ 51 = 5. So, 255 is divisible by 51. So, the answer is 51. or, Factors of 51 is = 17x3 Factors of 255 is = 3x5x17 So the common factors are 3x17 which is 51.
1, 3, 5 and 15
Factors of 51: 1 3 17 51 Factors of 255: 1 3 5 15 17 51 85 255 The GCF of 51 and 255 is 51
The factors of 255 are 1, 3, 5, 15, 17, 51, 85, and 255.
Factors of 136: 1, 2, 4, 8, 17, 34, 68, 136 Factors of 204: 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204 Factors of 255: 1, 3, 5, 15, 17, 51, 85, 255 GCF (136, 204, 255) = 17
The factors that they share. Example: 30 and 42 1,2,3,5,6,10,15,30 1,2,3,6,7,14,21,42 1,2,3 and 6 are the common factors, the factors in common.
The factors of 255 are:1 3 5 15 17 51 85 255The prime factors are: 3 x 5 x 171, 3, 5, 15, 17, 51, 85, 255
No, the only factors of 255 are 1, 3, 5, 15, 17, 51, 85, 255.
The least common multiple of the numbers 202 and 255 is 51,510.
The lowest common multiple (LCM) of 111 and 255 is 9435.
