Given numbers are 878, 861, 690, 755

The list of prime factors of all numbers are

Prime factors of 878 are 2 x 439

Prime factors of 861 are 3 x 7 x 41

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 755 are 5 x 151

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

Given numbers are 878, 861, 690, 755

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

Apply this formula for all numbers.

Step1:

LCM(878, 861) = 755958

GCD(878, 861) = ( 878 x 861 ) / 755958

= 878 / 861

= 878

Step2:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

Step3:

LCM(1, 755) = 755

GCD(1, 755) = ( 1 x 755 ) / 755

= 1 / 755

= 1

So, Greatest Common Divisor of 878, 861, 690, 755 is 1
