Given numbers are 985, 909, 981, 281

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

Apply this formula for all numbers.

Step1:

LCM(985, 909) = 895365

GCD(985, 909) = ( 985 x 909 ) / 895365

= 985 / 909

= 985

Step2:

LCM(1, 981) = 981

GCD(1, 981) = ( 1 x 981 ) / 981

= 1 / 981

= 1

Step3:

LCM(1, 281) = 281

GCD(1, 281) = ( 1 x 281 ) / 281

= 1 / 281

= 1

So, Greatest Common Divisor of 985, 909, 981, 281 is 1
