Given numbers are 645, 121, 989, 582

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(645, 121) = 78045

GCD(645, 121) = ( 645 x 121 ) / 78045

= 645 / 121

= 645

Step2:

LCM(1, 989) = 989

GCD(1, 989) = ( 1 x 989 ) / 989

= 1 / 989

= 1

Step3:

LCM(1, 582) = 582

GCD(1, 582) = ( 1 x 582 ) / 582

= 1 / 582

= 1

So, Greatest Common Divisor of 645, 121, 989, 582 is 1
