Given numbers are 125, 146, 105, 687

The list of prime factors of all numbers are

Prime factors of 125 are 5 x 5 x 5

Prime factors of 146 are 2 x 73

Prime factors of 105 are 3 x 5 x 7

Prime factors of 687 are 3 x 229

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

Given numbers are 125, 146, 105, 687

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

Apply this formula for all numbers.

Step1:

LCM(125, 146) = 18250

GCD(125, 146) = ( 125 x 146 ) / 18250

= 125 / 146

= 125

Step2:

LCM(1, 105) = 105

GCD(1, 105) = ( 1 x 105 ) / 105

= 1 / 105

= 1

Step3:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

So, Greatest Common Divisor of 125, 146, 105, 687 is 1
