GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(784, 812) = 22736
GCD(784, 812) = ( 784 x 812 ) / 22736
= 784 / 812
= 784
Step2:
LCM(28, 489) = 13692
GCD(28, 489) = ( 28 x 489 ) / 13692
= 28 / 489
= 28
Step3:
LCM(1, 979) = 979
GCD(1, 979) = ( 1 x 979 ) / 979
= 1 / 979
= 1
So, Greatest Common Divisor of 784, 812, 489, 979 is 1
