Given numbers are 613, 686, 640, 419

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

Apply this formula for all numbers.

Step1:

LCM(613, 686) = 420518

GCD(613, 686) = ( 613 x 686 ) / 420518

= 613 / 686

= 613

Step2:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

Step3:

LCM(1, 419) = 419

GCD(1, 419) = ( 1 x 419 ) / 419

= 1 / 419

= 1

So, Greatest Common Divisor of 613, 686, 640, 419 is 1
