Given numbers are 646, 621, 277

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

Apply this formula for all numbers.

Step1:

LCM(646, 621) = 401166

GCD(646, 621) = ( 646 x 621 ) / 401166

= 646 / 621

= 646

Step2:

LCM(1, 277) = 277

GCD(1, 277) = ( 1 x 277 ) / 277

= 1 / 277

= 1

So, Greatest Common Divisor of 646, 621, 277 is 1
