GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(643, 793) = 509899
GCD(643, 793) = ( 643 x 793 ) / 509899
= 643 / 793
= 643
Step2:
LCM(1, 896) = 896
GCD(1, 896) = ( 1 x 896 ) / 896
= 1 / 896
= 1
Step3:
LCM(1, 208) = 208
GCD(1, 208) = ( 1 x 208 ) / 208
= 1 / 208
= 1
So, Greatest Common Divisor of 643, 793, 896, 208 is 1
