Given numbers are 287, 245, 914, 981

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

Apply this formula for all numbers.

Step1:

LCM(287, 245) = 10045

GCD(287, 245) = ( 287 x 245 ) / 10045

= 287 / 245

= 287

Step2:

LCM(7, 914) = 6398

GCD(7, 914) = ( 7 x 914 ) / 6398

= 7 / 914

= 7

Step3:

LCM(1, 981) = 981

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

= 1 / 981

= 1

So, Greatest Common Divisor of 287, 245, 914, 981 is 1
