Given numbers are 390, 834, 731, 347

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

Apply this formula for all numbers.

Step1:

LCM(390, 834) = 54210

GCD(390, 834) = ( 390 x 834 ) / 54210

= 390 / 834

= 390

Step2:

LCM(6, 731) = 4386

GCD(6, 731) = ( 6 x 731 ) / 4386

= 6 / 731

= 6

Step3:

LCM(1, 347) = 347

GCD(1, 347) = ( 1 x 347 ) / 347

= 1 / 347

= 1

So, Greatest Common Divisor of 390, 834, 731, 347 is 1
