Given numbers are 390, 758, 10, 391

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

Apply this formula for all numbers.

Step1:

LCM(390, 758) = 147810

GCD(390, 758) = ( 390 x 758 ) / 147810

= 390 / 758

= 390

Step2:

LCM(2, 10) = 10

GCD(2, 10) = ( 2 x 10 ) / 10

= 2 / 10

= 2

Step3:

LCM(2, 391) = 782

GCD(2, 391) = ( 2 x 391 ) / 782

= 2 / 391

= 2

So, Greatest Common Divisor of 390, 758, 10, 391 is 1
