Given numbers are 407, 634, 861, 753

The list of prime factors of all numbers are

Prime factors of 407 are 11 x 37

Prime factors of 634 are 2 x 317

Prime factors of 861 are 3 x 7 x 41

Prime factors of 753 are 3 x 251

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

Given numbers are 407, 634, 861, 753

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

Apply this formula for all numbers.

Step1:

LCM(407, 634) = 258038

GCD(407, 634) = ( 407 x 634 ) / 258038

= 407 / 634

= 407

Step2:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

Step3:

LCM(1, 753) = 753

GCD(1, 753) = ( 1 x 753 ) / 753

= 1 / 753

= 1

So, Greatest Common Divisor of 407, 634, 861, 753 is 1
