Given numbers are 642, 380, 193, 554

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 380 are 2 x 2 x 5 x 19

Prime factors of 193 are 193

Prime factors of 554 are 2 x 277

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

Given numbers are 642, 380, 193, 554

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

Apply this formula for all numbers.

Step1:

LCM(642, 380) = 121980

GCD(642, 380) = ( 642 x 380 ) / 121980

= 642 / 380

= 642

Step2:

LCM(2, 193) = 386

GCD(2, 193) = ( 2 x 193 ) / 386

= 2 / 193

= 2

Step3:

LCM(1, 554) = 554

GCD(1, 554) = ( 1 x 554 ) / 554

= 1 / 554

= 1

So, Greatest Common Divisor of 642, 380, 193, 554 is 1
