Given numbers are 878, 654, 871, 684

The list of prime factors of all numbers are

Prime factors of 878 are 2 x 439

Prime factors of 654 are 2 x 3 x 109

Prime factors of 871 are 13 x 67

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

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

Given numbers are 878, 654, 871, 684

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

Apply this formula for all numbers.

Step1:

LCM(878, 654) = 287106

GCD(878, 654) = ( 878 x 654 ) / 287106

= 878 / 654

= 878

Step2:

LCM(2, 871) = 1742

GCD(2, 871) = ( 2 x 871 ) / 1742

= 2 / 871

= 2

Step3:

LCM(1, 684) = 684

GCD(1, 684) = ( 1 x 684 ) / 684

= 1 / 684

= 1

So, Greatest Common Divisor of 878, 654, 871, 684 is 1
