Given numbers are 579, 621, 215, 138

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

Apply this formula for all numbers.

Step1:

LCM(579, 621) = 119853

GCD(579, 621) = ( 579 x 621 ) / 119853

= 579 / 621

= 579

Step2:

LCM(3, 215) = 645

GCD(3, 215) = ( 3 x 215 ) / 645

= 3 / 215

= 3

Step3:

LCM(1, 138) = 138

GCD(1, 138) = ( 1 x 138 ) / 138

= 1 / 138

= 1

So, Greatest Common Divisor of 579, 621, 215, 138 is 1
