Given numbers are 191, 432, 113, 491
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(191, 432) = 82512
GCD(191, 432) = ( 191 x 432 ) / 82512
= 191 / 432
= 191
Step2:
LCM(1, 113) = 113
GCD(1, 113) = ( 1 x 113 ) / 113
= 1 / 113
= 1
Step3:
LCM(1, 491) = 491
GCD(1, 491) = ( 1 x 491 ) / 491
= 1 / 491
= 1
So, Greatest Common Divisor of 191, 432, 113, 491 is 1
