Given numbers are 621, 545, 646, 235

The list of prime factors of all numbers are

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 545 are 5 x 109

Prime factors of 646 are 2 x 17 x 19

Prime factors of 235 are 5 x 47

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

Given numbers are 621, 545, 646, 235

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

Apply this formula for all numbers.

Step1:

LCM(621, 545) = 338445

GCD(621, 545) = ( 621 x 545 ) / 338445

= 621 / 545

= 621

Step2:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

Step3:

LCM(1, 235) = 235

GCD(1, 235) = ( 1 x 235 ) / 235

= 1 / 235

= 1

So, Greatest Common Divisor of 621, 545, 646, 235 is 1
