Given numbers are 778, 810, 311, 775
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(778, 810) = 315090
GCD(778, 810) = ( 778 x 810 ) / 315090
= 778 / 810
= 778
Step2:
LCM(2, 311) = 622
GCD(2, 311) = ( 2 x 311 ) / 622
= 2 / 311
= 2
Step3:
LCM(1, 775) = 775
GCD(1, 775) = ( 1 x 775 ) / 775
= 1 / 775
= 1
So, Greatest Common Divisor of 778, 810, 311, 775 is 1
