Given numbers are 895, 450, 780, 687

The list of prime factors of all numbers are

Prime factors of 895 are 5 x 179

Prime factors of 450 are 2 x 3 x 3 x 5 x 5

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 687 are 3 x 229

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

Given numbers are 895, 450, 780, 687

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

Apply this formula for all numbers.

Step1:

LCM(895, 450) = 80550

GCD(895, 450) = ( 895 x 450 ) / 80550

= 895 / 450

= 895

Step2:

LCM(5, 780) = 780

GCD(5, 780) = ( 5 x 780 ) / 780

= 5 / 780

= 5

Step3:

LCM(5, 687) = 3435

GCD(5, 687) = ( 5 x 687 ) / 3435

= 5 / 687

= 5

So, Greatest Common Divisor of 895, 450, 780, 687 is 1
