Given numbers are 391, 840, 951, 181

The list of prime factors of all numbers are

Prime factors of 391 are 17 x 23

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 951 are 3 x 317

Prime factors of 181 are 181

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 391, 840, 951, 181

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

Apply this formula for all numbers.

Step1:

LCM(391, 840) = 328440

GCD(391, 840) = ( 391 x 840 ) / 328440

= 391 / 840

= 391

Step2:

LCM(1, 951) = 951

GCD(1, 951) = ( 1 x 951 ) / 951

= 1 / 951

= 1

Step3:

LCM(1, 181) = 181

GCD(1, 181) = ( 1 x 181 ) / 181

= 1 / 181

= 1

So, Greatest Common Divisor of 391, 840, 951, 181 is 1
