Given numbers are 347, 464, 155, 840

The list of prime factors of all numbers are

Prime factors of 347 are 347

Prime factors of 464 are 2 x 2 x 2 x 2 x 29

Prime factors of 155 are 5 x 31

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

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

Given numbers are 347, 464, 155, 840

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

Apply this formula for all numbers.

Step1:

LCM(347, 464) = 161008

GCD(347, 464) = ( 347 x 464 ) / 161008

= 347 / 464

= 347

Step2:

LCM(1, 155) = 155

GCD(1, 155) = ( 1 x 155 ) / 155

= 1 / 155

= 1

Step3:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

So, Greatest Common Divisor of 347, 464, 155, 840 is 1
