Given numbers are 399, 549, 263, 291

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

Apply this formula for all numbers.

Step1:

LCM(399, 549) = 73017

GCD(399, 549) = ( 399 x 549 ) / 73017

= 399 / 549

= 399

Step2:

LCM(3, 263) = 789

GCD(3, 263) = ( 3 x 263 ) / 789

= 3 / 263

= 3

Step3:

LCM(1, 291) = 291

GCD(1, 291) = ( 1 x 291 ) / 291

= 1 / 291

= 1

So, Greatest Common Divisor of 399, 549, 263, 291 is 1
