Given numbers are 878, 642, 180, 897

The list of prime factors of all numbers are

Prime factors of 878 are 2 x 439

Prime factors of 642 are 2 x 3 x 107

Prime factors of 180 are 2 x 2 x 3 x 3 x 5

Prime factors of 897 are 3 x 13 x 23

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

Given numbers are 878, 642, 180, 897

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

Apply this formula for all numbers.

Step1:

LCM(878, 642) = 281838

GCD(878, 642) = ( 878 x 642 ) / 281838

= 878 / 642

= 878

Step2:

LCM(2, 180) = 180

GCD(2, 180) = ( 2 x 180 ) / 180

= 2 / 180

= 2

Step3:

LCM(2, 897) = 1794

GCD(2, 897) = ( 2 x 897 ) / 1794

= 2 / 897

= 2

So, Greatest Common Divisor of 878, 642, 180, 897 is 1
