GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(989, 917) = 906913
GCD(989, 917) = ( 989 x 917 ) / 906913
= 989 / 917
= 989
Step2:
LCM(1, 785) = 785
GCD(1, 785) = ( 1 x 785 ) / 785
= 1 / 785
= 1
Step3:
LCM(1, 865) = 865
GCD(1, 865) = ( 1 x 865 ) / 865
= 1 / 865
= 1
So, Greatest Common Divisor of 989, 917, 785, 865 is 1
