Given numbers are 668, 546, 777, 398
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(668, 546) = 182364
GCD(668, 546) = ( 668 x 546 ) / 182364
= 668 / 546
= 668
Step2:
LCM(2, 777) = 1554
GCD(2, 777) = ( 2 x 777 ) / 1554
= 2 / 777
= 2
Step3:
LCM(1, 398) = 398
GCD(1, 398) = ( 1 x 398 ) / 398
= 1 / 398
= 1
So, Greatest Common Divisor of 668, 546, 777, 398 is 1
