Given numbers are 853, 379, 840, 155

The list of prime factors of all numbers are

Prime factors of 853 are 853

Prime factors of 379 are 379

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

Prime factors of 155 are 5 x 31

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

Given numbers are 853, 379, 840, 155

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

Apply this formula for all numbers.

Step1:

LCM(853, 379) = 323287

GCD(853, 379) = ( 853 x 379 ) / 323287

= 853 / 379

= 853

Step2:

LCM(1, 840) = 840

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

= 1 / 840

= 1

Step3:

LCM(1, 155) = 155

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

= 1 / 155

= 1

So, Greatest Common Divisor of 853, 379, 840, 155 is 1
