Given numbers are 242, 847, 90, 989

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

Apply this formula for all numbers.

Step1:

LCM(242, 847) = 1694

GCD(242, 847) = ( 242 x 847 ) / 1694

= 242 / 847

= 242

Step2:

LCM(121, 90) = 10890

GCD(121, 90) = ( 121 x 90 ) / 10890

= 121 / 90

= 121

Step3:

LCM(1, 989) = 989

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

= 1 / 989

= 1

So, Greatest Common Divisor of 242, 847, 90, 989 is 1
