Given numbers are 645, 538, 138, 150

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 538 are 2 x 269

Prime factors of 138 are 2 x 3 x 23

Prime factors of 150 are 2 x 3 x 5 x 5

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

Given numbers are 645, 538, 138, 150

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

Apply this formula for all numbers.

Step1:

LCM(645, 538) = 347010

GCD(645, 538) = ( 645 x 538 ) / 347010

= 645 / 538

= 645

Step2:

LCM(1, 138) = 138

GCD(1, 138) = ( 1 x 138 ) / 138

= 1 / 138

= 1

Step3:

LCM(1, 150) = 150

GCD(1, 150) = ( 1 x 150 ) / 150

= 1 / 150

= 1

So, Greatest Common Divisor of 645, 538, 138, 150 is 1
