GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(524, 728) = 95368
GCD(524, 728) = ( 524 x 728 ) / 95368
= 524 / 728
= 524
Step2:
LCM(4, 663) = 2652
GCD(4, 663) = ( 4 x 663 ) / 2652
= 4 / 663
= 4
Step3:
LCM(1, 640) = 640
GCD(1, 640) = ( 1 x 640 ) / 640
= 1 / 640
= 1
So, Greatest Common Divisor of 524, 728, 663, 640 is 1
