GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(556, 639) = 355284
GCD(556, 639) = ( 556 x 639 ) / 355284
= 556 / 639
= 556
Step2:
LCM(1, 621) = 621
GCD(1, 621) = ( 1 x 621 ) / 621
= 1 / 621
= 1
Step3:
LCM(1, 583) = 583
GCD(1, 583) = ( 1 x 583 ) / 583
= 1 / 583
= 1
So, Greatest Common Divisor of 556, 639, 621, 583 is 1
