Given numbers are 621, 668, 131, 617

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

Apply this formula for all numbers.

Step1:

LCM(621, 668) = 414828

GCD(621, 668) = ( 621 x 668 ) / 414828

= 621 / 668

= 621

Step2:

LCM(1, 131) = 131

GCD(1, 131) = ( 1 x 131 ) / 131

= 1 / 131

= 1

Step3:

LCM(1, 617) = 617

GCD(1, 617) = ( 1 x 617 ) / 617

= 1 / 617

= 1

So, Greatest Common Divisor of 621, 668, 131, 617 is 1
