GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(668, 728) = 121576
GCD(668, 728) = ( 668 x 728 ) / 121576
= 668 / 728
= 668
Step2:
LCM(4, 864) = 864
GCD(4, 864) = ( 4 x 864 ) / 864
= 4 / 864
= 4
Step3:
LCM(4, 416) = 416
GCD(4, 416) = ( 4 x 416 ) / 416
= 4 / 416
= 4
So, Greatest Common Divisor of 668, 728, 864, 416 is 4
