Given numbers are 390, 639, 538, 323

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

Apply this formula for all numbers.

Step1:

LCM(390, 639) = 83070

GCD(390, 639) = ( 390 x 639 ) / 83070

= 390 / 639

= 390

Step2:

LCM(3, 538) = 1614

GCD(3, 538) = ( 3 x 538 ) / 1614

= 3 / 538

= 3

Step3:

LCM(1, 323) = 323

GCD(1, 323) = ( 1 x 323 ) / 323

= 1 / 323

= 1

So, Greatest Common Divisor of 390, 639, 538, 323 is 1
