Given numbers are 390, 310, 719, 915

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

Apply this formula for all numbers.

Step1:

LCM(390, 310) = 12090

GCD(390, 310) = ( 390 x 310 ) / 12090

= 390 / 310

= 390

Step2:

LCM(10, 719) = 7190

GCD(10, 719) = ( 10 x 719 ) / 7190

= 10 / 719

= 10

Step3:

LCM(1, 915) = 915

GCD(1, 915) = ( 1 x 915 ) / 915

= 1 / 915

= 1

So, Greatest Common Divisor of 390, 310, 719, 915 is 1
