Given numbers are 668, 394, 338, 491
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(668, 394) = 131596
GCD(668, 394) = ( 668 x 394 ) / 131596
= 668 / 394
= 668
Step2:
LCM(2, 338) = 338
GCD(2, 338) = ( 2 x 338 ) / 338
= 2 / 338
= 2
Step3:
LCM(2, 491) = 982
GCD(2, 491) = ( 2 x 491 ) / 982
= 2 / 491
= 2
So, Greatest Common Divisor of 668, 394, 338, 491 is 1
