Given numbers are 515, 815, 353, 743

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

Apply this formula for all numbers.

Step1:

LCM(515, 815) = 83945

GCD(515, 815) = ( 515 x 815 ) / 83945

= 515 / 815

= 515

Step2:

LCM(5, 353) = 1765

GCD(5, 353) = ( 5 x 353 ) / 1765

= 5 / 353

= 5

Step3:

LCM(1, 743) = 743

GCD(1, 743) = ( 1 x 743 ) / 743

= 1 / 743

= 1

So, Greatest Common Divisor of 515, 815, 353, 743 is 1
