Given numbers are 105, 647, 985, 960

The list of prime factors of all numbers are

Prime factors of 105 are 3 x 5 x 7

Prime factors of 647 are 647

Prime factors of 985 are 5 x 197

Prime factors of 960 are 2 x 2 x 2 x 2 x 2 x 2 x 3 x 5

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 105, 647, 985, 960

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(105, 647) = 67935

GCD(105, 647) = ( 105 x 647 ) / 67935

= 105 / 647

= 105

Step2:

LCM(1, 985) = 985

GCD(1, 985) = ( 1 x 985 ) / 985

= 1 / 985

= 1

Step3:

LCM(1, 960) = 960

GCD(1, 960) = ( 1 x 960 ) / 960

= 1 / 960

= 1

So, Greatest Common Divisor of 105, 647, 985, 960 is 1
