Given numbers are 391, 555, 850, 160

The list of prime factors of all numbers are

Prime factors of 391 are 17 x 23

Prime factors of 555 are 3 x 5 x 37

Prime factors of 850 are 2 x 5 x 5 x 17

Prime factors of 160 are 2 x 2 x 2 x 2 x 2 x 5

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

Given numbers are 391, 555, 850, 160

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

Apply this formula for all numbers.

Step1:

LCM(391, 555) = 217005

GCD(391, 555) = ( 391 x 555 ) / 217005

= 391 / 555

= 391

Step2:

LCM(1, 850) = 850

GCD(1, 850) = ( 1 x 850 ) / 850

= 1 / 850

= 1

Step3:

LCM(1, 160) = 160

GCD(1, 160) = ( 1 x 160 ) / 160

= 1 / 160

= 1

So, Greatest Common Divisor of 391, 555, 850, 160 is 1
