Given numbers are 247, 113, 462, 921
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(247, 113) = 27911
GCD(247, 113) = ( 247 x 113 ) / 27911
= 247 / 113
= 247
Step2:
LCM(1, 462) = 462
GCD(1, 462) = ( 1 x 462 ) / 462
= 1 / 462
= 1
Step3:
LCM(1, 921) = 921
GCD(1, 921) = ( 1 x 921 ) / 921
= 1 / 921
= 1
So, Greatest Common Divisor of 247, 113, 462, 921 is 1
