Given numbers are 390, 808, 297, 828

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

Apply this formula for all numbers.

Step1:

LCM(390, 808) = 157560

GCD(390, 808) = ( 390 x 808 ) / 157560

= 390 / 808

= 390

Step2:

LCM(2, 297) = 594

GCD(2, 297) = ( 2 x 297 ) / 594

= 2 / 297

= 2

Step3:

LCM(1, 828) = 828

GCD(1, 828) = ( 1 x 828 ) / 828

= 1 / 828

= 1

So, Greatest Common Divisor of 390, 808, 297, 828 is 1
