GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(308, 828) = 63756
GCD(308, 828) = ( 308 x 828 ) / 63756
= 308 / 828
= 308
Step2:
LCM(4, 640) = 640
GCD(4, 640) = ( 4 x 640 ) / 640
= 4 / 640
= 4
Step3:
LCM(4, 863) = 3452
GCD(4, 863) = ( 4 x 863 ) / 3452
= 4 / 863
= 4
So, Greatest Common Divisor of 308, 828, 640, 863 is 1
