Given numbers are 778, 511, 773, 210
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(778, 511) = 397558
GCD(778, 511) = ( 778 x 511 ) / 397558
= 778 / 511
= 778
Step2:
LCM(1, 773) = 773
GCD(1, 773) = ( 1 x 773 ) / 773
= 1 / 773
= 1
Step3:
LCM(1, 210) = 210
GCD(1, 210) = ( 1 x 210 ) / 210
= 1 / 210
= 1
So, Greatest Common Divisor of 778, 511, 773, 210 is 1
