Given numbers are 254, 643, 656, 134

The list of prime factors of all numbers are

Prime factors of 254 are 2 x 127

Prime factors of 643 are 643

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

Prime factors of 134 are 2 x 67

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

Given numbers are 254, 643, 656, 134

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

Apply this formula for all numbers.

Step1:

LCM(254, 643) = 163322

GCD(254, 643) = ( 254 x 643 ) / 163322

= 254 / 643

= 254

Step2:

LCM(1, 656) = 656

GCD(1, 656) = ( 1 x 656 ) / 656

= 1 / 656

= 1

Step3:

LCM(1, 134) = 134

GCD(1, 134) = ( 1 x 134 ) / 134

= 1 / 134

= 1

So, Greatest Common Divisor of 254, 643, 656, 134 is 1
