Given numbers are 860, 355, 145, 203

The list of prime factors of all numbers are

Prime factors of 860 are 2 x 2 x 5 x 43

Prime factors of 355 are 5 x 71

Prime factors of 145 are 5 x 29

Prime factors of 203 are 7 x 29

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

Given numbers are 860, 355, 145, 203

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

Apply this formula for all numbers.

Step1:

LCM(860, 355) = 61060

GCD(860, 355) = ( 860 x 355 ) / 61060

= 860 / 355

= 860

Step2:

LCM(5, 145) = 145

GCD(5, 145) = ( 5 x 145 ) / 145

= 5 / 145

= 5

Step3:

LCM(5, 203) = 1015

GCD(5, 203) = ( 5 x 203 ) / 1015

= 5 / 203

= 5

So, Greatest Common Divisor of 860, 355, 145, 203 is 1
