GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(663, 928) = 615264
GCD(663, 928) = ( 663 x 928 ) / 615264
= 663 / 928
= 663
Step2:
LCM(1, 583) = 583
GCD(1, 583) = ( 1 x 583 ) / 583
= 1 / 583
= 1
Step3:
LCM(1, 821) = 821
GCD(1, 821) = ( 1 x 821 ) / 821
= 1 / 821
= 1
So, Greatest Common Divisor of 663, 928, 583, 821 is 1
