Given numbers are 987, 318, 181, 203

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

Apply this formula for all numbers.

Step1:

LCM(987, 318) = 104622

GCD(987, 318) = ( 987 x 318 ) / 104622

= 987 / 318

= 987

Step2:

LCM(3, 181) = 543

GCD(3, 181) = ( 3 x 181 ) / 543

= 3 / 181

= 3

Step3:

LCM(1, 203) = 203

GCD(1, 203) = ( 1 x 203 ) / 203

= 1 / 203

= 1

So, Greatest Common Divisor of 987, 318, 181, 203 is 1
