Given numbers are 646, 421, 157, 493

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

Apply this formula for all numbers.

Step1:

LCM(646, 421) = 271966

GCD(646, 421) = ( 646 x 421 ) / 271966

= 646 / 421

= 646

Step2:

LCM(1, 157) = 157

GCD(1, 157) = ( 1 x 157 ) / 157

= 1 / 157

= 1

Step3:

LCM(1, 493) = 493

GCD(1, 493) = ( 1 x 493 ) / 493

= 1 / 493

= 1

So, Greatest Common Divisor of 646, 421, 157, 493 is 1
