Given numbers are 651, 405, 677, 871

The list of prime factors of all numbers are

Prime factors of 651 are 3 x 7 x 31

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

Prime factors of 677 are 677

Prime factors of 871 are 13 x 67

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

Given numbers are 651, 405, 677, 871

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

Apply this formula for all numbers.

Step1:

LCM(651, 405) = 87885

GCD(651, 405) = ( 651 x 405 ) / 87885

= 651 / 405

= 651

Step2:

LCM(3, 677) = 2031

GCD(3, 677) = ( 3 x 677 ) / 2031

= 3 / 677

= 3

Step3:

LCM(1, 871) = 871

GCD(1, 871) = ( 1 x 871 ) / 871

= 1 / 871

= 1

So, Greatest Common Divisor of 651, 405, 677, 871 is 1
