Given numbers are 644, 204, 135, 274

The list of prime factors of all numbers are

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 204 are 2 x 2 x 3 x 17

Prime factors of 135 are 3 x 3 x 3 x 5

Prime factors of 274 are 2 x 137

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

Given numbers are 644, 204, 135, 274

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

Apply this formula for all numbers.

Step1:

LCM(644, 204) = 32844

GCD(644, 204) = ( 644 x 204 ) / 32844

= 644 / 204

= 644

Step2:

LCM(4, 135) = 540

GCD(4, 135) = ( 4 x 135 ) / 540

= 4 / 135

= 4

Step3:

LCM(1, 274) = 274

GCD(1, 274) = ( 1 x 274 ) / 274

= 1 / 274

= 1

So, Greatest Common Divisor of 644, 204, 135, 274 is 1
