Given numbers are 621, 515, 779

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

Apply this formula for all numbers.

Step1:

LCM(621, 515) = 319815

GCD(621, 515) = ( 621 x 515 ) / 319815

= 621 / 515

= 621

Step2:

LCM(1, 779) = 779

GCD(1, 779) = ( 1 x 779 ) / 779

= 1 / 779

= 1

So, Greatest Common Divisor of 621, 515, 779 is 1
