Given numbers are 642, 136, 792, 181

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

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

Prime factors of 792 are 2 x 2 x 2 x 3 x 3 x 11

Prime factors of 181 are 181

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

Given numbers are 642, 136, 792, 181

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

Apply this formula for all numbers.

Step1:

LCM(642, 136) = 43656

GCD(642, 136) = ( 642 x 136 ) / 43656

= 642 / 136

= 642

Step2:

LCM(2, 792) = 792

GCD(2, 792) = ( 2 x 792 ) / 792

= 2 / 792

= 2

Step3:

LCM(2, 181) = 362

GCD(2, 181) = ( 2 x 181 ) / 362

= 2 / 181

= 2

So, Greatest Common Divisor of 642, 136, 792, 181 is 1
