GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(394, 128) = 25216
GCD(394, 128) = ( 394 x 128 ) / 25216
= 394 / 128
= 394
Step2:
LCM(2, 729) = 1458
GCD(2, 729) = ( 2 x 729 ) / 1458
= 2 / 729
= 2
Step3:
LCM(1, 698) = 698
GCD(1, 698) = ( 1 x 698 ) / 698
= 1 / 698
= 1
So, Greatest Common Divisor of 394, 128, 729, 698 is 1
