Given numbers are 897, 698, 454, 989
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(897, 698) = 626106
GCD(897, 698) = ( 897 x 698 ) / 626106
= 897 / 698
= 897
Step2:
LCM(1, 454) = 454
GCD(1, 454) = ( 1 x 454 ) / 454
= 1 / 454
= 1
Step3:
LCM(1, 989) = 989
GCD(1, 989) = ( 1 x 989 ) / 989
= 1 / 989
= 1
So, Greatest Common Divisor of 897, 698, 454, 989 is 1
