Given numbers are 981, 678, 328, 135

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

Apply this formula for all numbers.

Step1:

LCM(981, 678) = 221706

GCD(981, 678) = ( 981 x 678 ) / 221706

= 981 / 678

= 981

Step2:

LCM(3, 328) = 984

GCD(3, 328) = ( 3 x 328 ) / 984

= 3 / 328

= 3

Step3:

LCM(1, 135) = 135

GCD(1, 135) = ( 1 x 135 ) / 135

= 1 / 135

= 1

So, Greatest Common Divisor of 981, 678, 328, 135 is 1
