GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(168, 640) = 13440
GCD(168, 640) = ( 168 x 640 ) / 13440
= 168 / 640
= 168
Step2:
LCM(8, 474) = 1896
GCD(8, 474) = ( 8 x 474 ) / 1896
= 8 / 474
= 8
Step3:
LCM(2, 714) = 714
GCD(2, 714) = ( 2 x 714 ) / 714
= 2 / 714
= 2
So, Greatest Common Divisor of 168, 640, 474, 714 is 2
