GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(897, 640) = 574080
GCD(897, 640) = ( 897 x 640 ) / 574080
= 897 / 640
= 897
Step2:
LCM(1, 843) = 843
GCD(1, 843) = ( 1 x 843 ) / 843
= 1 / 843
= 1
Step3:
LCM(1, 816) = 816
GCD(1, 816) = ( 1 x 816 ) / 816
= 1 / 816
= 1
So, Greatest Common Divisor of 897, 640, 843, 816 is 1
