Given numbers are 399, 642, 526, 917

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

Apply this formula for all numbers.

Step1:

LCM(399, 642) = 85386

GCD(399, 642) = ( 399 x 642 ) / 85386

= 399 / 642

= 399

Step2:

LCM(3, 526) = 1578

GCD(3, 526) = ( 3 x 526 ) / 1578

= 3 / 526

= 3

Step3:

LCM(1, 917) = 917

GCD(1, 917) = ( 1 x 917 ) / 917

= 1 / 917

= 1

So, Greatest Common Divisor of 399, 642, 526, 917 is 1
