Given numbers are 981, 825, 203, 281

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

Apply this formula for all numbers.

Step1:

LCM(981, 825) = 269775

GCD(981, 825) = ( 981 x 825 ) / 269775

= 981 / 825

= 981

Step2:

LCM(3, 203) = 609

GCD(3, 203) = ( 3 x 203 ) / 609

= 3 / 203

= 3

Step3:

LCM(1, 281) = 281

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

= 1 / 281

= 1

So, Greatest Common Divisor of 981, 825, 203, 281 is 1
