Given numbers are 136, 554, 387, 638

The list of prime factors of all numbers are

Prime factors of 136 are 2 x 2 x 2 x 17

Prime factors of 554 are 2 x 277

Prime factors of 387 are 3 x 3 x 43

Prime factors of 638 are 2 x 11 x 29

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

Given numbers are 136, 554, 387, 638

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

Apply this formula for all numbers.

Step1:

LCM(136, 554) = 37672

GCD(136, 554) = ( 136 x 554 ) / 37672

= 136 / 554

= 136

Step2:

LCM(2, 387) = 774

GCD(2, 387) = ( 2 x 387 ) / 774

= 2 / 387

= 2

Step3:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

So, Greatest Common Divisor of 136, 554, 387, 638 is 1
