Given numbers are 442, 343, 515

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

Apply this formula for all numbers.

Step1:

LCM(442, 343) = 151606

GCD(442, 343) = ( 442 x 343 ) / 151606

= 442 / 343

= 442

Step2:

LCM(1, 515) = 515

GCD(1, 515) = ( 1 x 515 ) / 515

= 1 / 515

= 1

So, Greatest Common Divisor of 442, 343, 515 is 1
