Given numbers are 515, 742, 381

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

Apply this formula for all numbers.

Step1:

LCM(515, 742) = 382130

GCD(515, 742) = ( 515 x 742 ) / 382130

= 515 / 742

= 515

Step2:

LCM(1, 381) = 381

GCD(1, 381) = ( 1 x 381 ) / 381

= 1 / 381

= 1

So, Greatest Common Divisor of 515, 742, 381 is 1
