Given numbers are 989, 649, 124, 851
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(989, 649) = 641861
GCD(989, 649) = ( 989 x 649 ) / 641861
= 989 / 649
= 989
Step2:
LCM(1, 124) = 124
GCD(1, 124) = ( 1 x 124 ) / 124
= 1 / 124
= 1
Step3:
LCM(1, 851) = 851
GCD(1, 851) = ( 1 x 851 ) / 851
= 1 / 851
= 1
So, Greatest Common Divisor of 989, 649, 124, 851 is 1
