Given numbers are 987, 365, 915

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

Apply this formula for all numbers.

Step1:

LCM(987, 365) = 360255

GCD(987, 365) = ( 987 x 365 ) / 360255

= 987 / 365

= 987

Step2:

LCM(1, 915) = 915

GCD(1, 915) = ( 1 x 915 ) / 915

= 1 / 915

= 1

So, Greatest Common Divisor of 987, 365, 915 is 1
