Given numbers are 421, 646, 406, 325

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

Apply this formula for all numbers.

Step1:

LCM(421, 646) = 271966

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

= 421 / 646

= 421

Step2:

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

= 1 / 406

= 1

Step3:

LCM(1, 325) = 325

GCD(1, 325) = ( 1 x 325 ) / 325

= 1 / 325

= 1

So, Greatest Common Divisor of 421, 646, 406, 325 is 1
