Given numbers are 730, 728, 778, 819
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(730, 728) = 265720
GCD(730, 728) = ( 730 x 728 ) / 265720
= 730 / 728
= 730
Step2:
LCM(2, 778) = 778
GCD(2, 778) = ( 2 x 778 ) / 778
= 2 / 778
= 2
Step3:
LCM(2, 819) = 1638
GCD(2, 819) = ( 2 x 819 ) / 1638
= 2 / 819
= 2
So, Greatest Common Divisor of 730, 728, 778, 819 is 1
