Given numbers are 399, 831, 131, 156

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

Apply this formula for all numbers.

Step1:

LCM(399, 831) = 110523

GCD(399, 831) = ( 399 x 831 ) / 110523

= 399 / 831

= 399

Step2:

LCM(3, 131) = 393

GCD(3, 131) = ( 3 x 131 ) / 393

= 3 / 131

= 3

Step3:

LCM(1, 156) = 156

GCD(1, 156) = ( 1 x 156 ) / 156

= 1 / 156

= 1

So, Greatest Common Divisor of 399, 831, 131, 156 is 1
