Given numbers are 981, 342, 118, 289

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

Apply this formula for all numbers.

Step1:

LCM(981, 342) = 37278

GCD(981, 342) = ( 981 x 342 ) / 37278

= 981 / 342

= 981

Step2:

LCM(9, 118) = 1062

GCD(9, 118) = ( 9 x 118 ) / 1062

= 9 / 118

= 9

Step3:

LCM(1, 289) = 289

GCD(1, 289) = ( 1 x 289 ) / 289

= 1 / 289

= 1

So, Greatest Common Divisor of 981, 342, 118, 289 is 1
