Given numbers are 865, 861, 759, 761

The list of prime factors of all numbers are

Prime factors of 865 are 5 x 173

Prime factors of 861 are 3 x 7 x 41

Prime factors of 759 are 3 x 11 x 23

Prime factors of 761 are 761

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

Given numbers are 865, 861, 759, 761

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

Apply this formula for all numbers.

Step1:

LCM(865, 861) = 744765

GCD(865, 861) = ( 865 x 861 ) / 744765

= 865 / 861

= 865

Step2:

LCM(1, 759) = 759

GCD(1, 759) = ( 1 x 759 ) / 759

= 1 / 759

= 1

Step3:

LCM(1, 761) = 761

GCD(1, 761) = ( 1 x 761 ) / 761

= 1 / 761

= 1

So, Greatest Common Divisor of 865, 861, 759, 761 is 1
