GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(191, 836) = 159676
GCD(191, 836) = ( 191 x 836 ) / 159676
= 191 / 836
= 191
Step2:
LCM(1, 319) = 319
GCD(1, 319) = ( 1 x 319 ) / 319
= 1 / 319
= 1
Step3:
LCM(1, 638) = 638
GCD(1, 638) = ( 1 x 638 ) / 638
= 1 / 638
= 1
So, Greatest Common Divisor of 191, 836, 319, 638 is 1
