Given numbers are 562, 840, 407, 687

The list of prime factors of all numbers are

Prime factors of 562 are 2 x 281

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 407 are 11 x 37

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 562, 840, 407, 687

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

Apply this formula for all numbers.

Step1:

LCM(562, 840) = 236040

GCD(562, 840) = ( 562 x 840 ) / 236040

= 562 / 840

= 562

Step2:

LCM(2, 407) = 814

GCD(2, 407) = ( 2 x 407 ) / 814

= 2 / 407

= 2

Step3:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

So, Greatest Common Divisor of 562, 840, 407, 687 is 1
