Given numbers are 778, 408, 676, 731
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(778, 408) = 158712
GCD(778, 408) = ( 778 x 408 ) / 158712
= 778 / 408
= 778
Step2:
LCM(2, 676) = 676
GCD(2, 676) = ( 2 x 676 ) / 676
= 2 / 676
= 2
Step3:
LCM(2, 731) = 1462
GCD(2, 731) = ( 2 x 731 ) / 1462
= 2 / 731
= 2
So, Greatest Common Divisor of 778, 408, 676, 731 is 1
