Given numbers are 125, 540, 122, 645

The list of prime factors of all numbers are

Prime factors of 125 are 5 x 5 x 5

Prime factors of 540 are 2 x 2 x 3 x 3 x 3 x 5

Prime factors of 122 are 2 x 61

Prime factors of 645 are 3 x 5 x 43

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

Given numbers are 125, 540, 122, 645

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

Apply this formula for all numbers.

Step1:

LCM(125, 540) = 13500

GCD(125, 540) = ( 125 x 540 ) / 13500

= 125 / 540

= 125

Step2:

LCM(5, 122) = 610

GCD(5, 122) = ( 5 x 122 ) / 610

= 5 / 122

= 5

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 125, 540, 122, 645 is 1
