Given numbers are 605, 715, 987

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

Apply this formula for all numbers.

Step1:

LCM(605, 715) = 7865

GCD(605, 715) = ( 605 x 715 ) / 7865

= 605 / 715

= 605

Step2:

LCM(55, 987) = 54285

GCD(55, 987) = ( 55 x 987 ) / 54285

= 55 / 987

= 55

So, Greatest Common Divisor of 605, 715, 987 is 1
