Given numbers are 445, 690, 871, 678

The list of prime factors of all numbers are

Prime factors of 445 are 5 x 89

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

Prime factors of 871 are 13 x 67

Prime factors of 678 are 2 x 3 x 113

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

Given numbers are 445, 690, 871, 678

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

Apply this formula for all numbers.

Step1:

LCM(445, 690) = 61410

GCD(445, 690) = ( 445 x 690 ) / 61410

= 445 / 690

= 445

Step2:

LCM(5, 871) = 4355

GCD(5, 871) = ( 5 x 871 ) / 4355

= 5 / 871

= 5

Step3:

LCM(1, 678) = 678

GCD(1, 678) = ( 1 x 678 ) / 678

= 1 / 678

= 1

So, Greatest Common Divisor of 445, 690, 871, 678 is 1
