GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(668, 639) = 426852
GCD(668, 639) = ( 668 x 639 ) / 426852
= 668 / 639
= 668
Step2:
LCM(1, 416) = 416
GCD(1, 416) = ( 1 x 416 ) / 416
= 1 / 416
= 1
Step3:
LCM(1, 532) = 532
GCD(1, 532) = ( 1 x 532 ) / 532
= 1 / 532
= 1
So, Greatest Common Divisor of 668, 639, 416, 532 is 1
