GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 798) = 255360
GCD(640, 798) = ( 640 x 798 ) / 255360
= 640 / 798
= 640
Step2:
LCM(2, 326) = 326
GCD(2, 326) = ( 2 x 326 ) / 326
= 2 / 326
= 2
Step3:
LCM(2, 816) = 816
GCD(2, 816) = ( 2 x 816 ) / 816
= 2 / 816
= 2
So, Greatest Common Divisor of 640, 798, 326, 816 is 2
