Given numbers are 518, 461, 389, 778
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(518, 461) = 238798
GCD(518, 461) = ( 518 x 461 ) / 238798
= 518 / 461
= 518
Step2:
LCM(1, 389) = 389
GCD(1, 389) = ( 1 x 389 ) / 389
= 1 / 389
= 1
Step3:
LCM(1, 778) = 778
GCD(1, 778) = ( 1 x 778 ) / 778
= 1 / 778
= 1
So, Greatest Common Divisor of 518, 461, 389, 778 is 1
