Given numbers are 398, 120, 667, 979
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 120) = 23880
GCD(398, 120) = ( 398 x 120 ) / 23880
= 398 / 120
= 398
Step2:
LCM(2, 667) = 1334
GCD(2, 667) = ( 2 x 667 ) / 1334
= 2 / 667
= 2
Step3:
LCM(1, 979) = 979
GCD(1, 979) = ( 1 x 979 ) / 979
= 1 / 979
= 1
So, Greatest Common Divisor of 398, 120, 667, 979 is 1
