Given numbers are 987, 871, 445

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

Apply this formula for all numbers.

Step1:

LCM(987, 871) = 859677

GCD(987, 871) = ( 987 x 871 ) / 859677

= 987 / 871

= 987

Step2:

LCM(1, 445) = 445

GCD(1, 445) = ( 1 x 445 ) / 445

= 1 / 445

= 1

So, Greatest Common Divisor of 987, 871, 445 is 1
