Given numbers are 345, 840, 127, 291

The list of prime factors of all numbers are

Prime factors of 345 are 3 x 5 x 23

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

Prime factors of 127 are 127

Prime factors of 291 are 3 x 97

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

Given numbers are 345, 840, 127, 291

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

Apply this formula for all numbers.

Step1:

LCM(345, 840) = 19320

GCD(345, 840) = ( 345 x 840 ) / 19320

= 345 / 840

= 345

Step2:

LCM(15, 127) = 1905

GCD(15, 127) = ( 15 x 127 ) / 1905

= 15 / 127

= 15

Step3:

LCM(1, 291) = 291

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

= 1 / 291

= 1

So, Greatest Common Divisor of 345, 840, 127, 291 is 1
