Given numbers are 853, 155, 189, 840

The list of prime factors of all numbers are

Prime factors of 853 are 853

Prime factors of 155 are 5 x 31

Prime factors of 189 are 3 x 3 x 3 x 7

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 853, 155, 189, 840

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

Apply this formula for all numbers.

Step1:

LCM(853, 155) = 132215

GCD(853, 155) = ( 853 x 155 ) / 132215

= 853 / 155

= 853

Step2:

LCM(1, 189) = 189

GCD(1, 189) = ( 1 x 189 ) / 189

= 1 / 189

= 1

Step3:

LCM(1, 840) = 840

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

= 1 / 840

= 1

So, Greatest Common Divisor of 853, 155, 189, 840 is 1
