Given numbers are 861, 753, 253, 417

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 753 are 3 x 251

Prime factors of 253 are 11 x 23

Prime factors of 417 are 3 x 139

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

Given numbers are 861, 753, 253, 417

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

Apply this formula for all numbers.

Step1:

LCM(861, 753) = 216111

GCD(861, 753) = ( 861 x 753 ) / 216111

= 861 / 753

= 861

Step2:

LCM(3, 253) = 759

GCD(3, 253) = ( 3 x 253 ) / 759

= 3 / 253

= 3

Step3:

LCM(1, 417) = 417

GCD(1, 417) = ( 1 x 417 ) / 417

= 1 / 417

= 1

So, Greatest Common Divisor of 861, 753, 253, 417 is 1
