Given numbers are 515, 380, 209, 931

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

Apply this formula for all numbers.

Step1:

LCM(515, 380) = 39140

GCD(515, 380) = ( 515 x 380 ) / 39140

= 515 / 380

= 515

Step2:

LCM(5, 209) = 1045

GCD(5, 209) = ( 5 x 209 ) / 1045

= 5 / 209

= 5

Step3:

LCM(1, 931) = 931

GCD(1, 931) = ( 1 x 931 ) / 931

= 1 / 931

= 1

So, Greatest Common Divisor of 515, 380, 209, 931 is 1
