Given numbers are 125, 165, 646, 635

The list of prime factors of all numbers are

Prime factors of 125 are 5 x 5 x 5

Prime factors of 165 are 3 x 5 x 11

Prime factors of 646 are 2 x 17 x 19

Prime factors of 635 are 5 x 127

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

Given numbers are 125, 165, 646, 635

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

Apply this formula for all numbers.

Step1:

LCM(125, 165) = 4125

GCD(125, 165) = ( 125 x 165 ) / 4125

= 125 / 165

= 125

Step2:

LCM(5, 646) = 3230

GCD(5, 646) = ( 5 x 646 ) / 3230

= 5 / 646

= 5

Step3:

LCM(1, 635) = 635

GCD(1, 635) = ( 1 x 635 ) / 635

= 1 / 635

= 1

So, Greatest Common Divisor of 125, 165, 646, 635 is 1
