Given numbers are 191, 520, 645, 498
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(191, 520) = 99320
GCD(191, 520) = ( 191 x 520 ) / 99320
= 191 / 520
= 191
Step2:
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
= 1 / 645
= 1
Step3:
LCM(1, 498) = 498
GCD(1, 498) = ( 1 x 498 ) / 498
= 1 / 498
= 1
So, Greatest Common Divisor of 191, 520, 645, 498 is 1
