GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(647, 344) = 222568
GCD(647, 344) = ( 647 x 344 ) / 222568
= 647 / 344
= 647
Step2:
LCM(1, 893) = 893
GCD(1, 893) = ( 1 x 893 ) / 893
= 1 / 893
= 1
Step3:
LCM(1, 720) = 720
GCD(1, 720) = ( 1 x 720 ) / 720
= 1 / 720
= 1
So, Greatest Common Divisor of 647, 344, 893, 720 is 1
