Given numbers are 668, 123, 778, 476
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(668, 123) = 82164
GCD(668, 123) = ( 668 x 123 ) / 82164
= 668 / 123
= 668
Step2:
LCM(1, 778) = 778
GCD(1, 778) = ( 1 x 778 ) / 778
= 1 / 778
= 1
Step3:
LCM(1, 476) = 476
GCD(1, 476) = ( 1 x 476 ) / 476
= 1 / 476
= 1
So, Greatest Common Divisor of 668, 123, 778, 476 is 1
