Given numbers are 989, 621, 853, 611
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(989, 621) = 26703
GCD(989, 621) = ( 989 x 621 ) / 26703
= 989 / 621
= 989
Step2:
LCM(23, 853) = 19619
GCD(23, 853) = ( 23 x 853 ) / 19619
= 23 / 853
= 23
Step3:
LCM(1, 611) = 611
GCD(1, 611) = ( 1 x 611 ) / 611
= 1 / 611
= 1
So, Greatest Common Divisor of 989, 621, 853, 611 is 1
