GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(897, 939) = 280761
GCD(897, 939) = ( 897 x 939 ) / 280761
= 897 / 939
= 897
Step2:
LCM(3, 689) = 2067
GCD(3, 689) = ( 3 x 689 ) / 2067
= 3 / 689
= 3
Step3:
LCM(1, 678) = 678
GCD(1, 678) = ( 1 x 678 ) / 678
= 1 / 678
= 1
So, Greatest Common Divisor of 897, 939, 689, 678 is 1
