GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(643, 896) = 576128
GCD(643, 896) = ( 643 x 896 ) / 576128
= 643 / 896
= 643
Step2:
LCM(1, 461) = 461
GCD(1, 461) = ( 1 x 461 ) / 461
= 1 / 461
= 1
Step3:
LCM(1, 939) = 939
GCD(1, 939) = ( 1 x 939 ) / 939
= 1 / 939
= 1
So, Greatest Common Divisor of 643, 896, 461, 939 is 1
