Given numbers are 391, 477, 667, 822
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(391, 477) = 186507
GCD(391, 477) = ( 391 x 477 ) / 186507
= 391 / 477
= 391
Step2:
LCM(1, 667) = 667
GCD(1, 667) = ( 1 x 667 ) / 667
= 1 / 667
= 1
Step3:
LCM(1, 822) = 822
GCD(1, 822) = ( 1 x 822 ) / 822
= 1 / 822
= 1
So, Greatest Common Divisor of 391, 477, 667, 822 is 1
