GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(491, 627) = 307857
GCD(491, 627) = ( 491 x 627 ) / 307857
= 491 / 627
= 491
Step2:
LCM(1, 528) = 528
GCD(1, 528) = ( 1 x 528 ) / 528
= 1 / 528
= 1
Step3:
LCM(1, 663) = 663
GCD(1, 663) = ( 1 x 663 ) / 663
= 1 / 663
= 1
So, Greatest Common Divisor of 491, 627, 528, 663 is 1
