Given numbers are 677, 620, 221, 629

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

Apply this formula for all numbers.

Step1:

LCM(677, 620) = 419740

GCD(677, 620) = ( 677 x 620 ) / 419740

= 677 / 620

= 677

Step2:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

Step3:

LCM(1, 629) = 629

GCD(1, 629) = ( 1 x 629 ) / 629

= 1 / 629

= 1

So, Greatest Common Divisor of 677, 620, 221, 629 is 1
