Given numbers are 814, 642, 715, 624

The list of prime factors of all numbers are

Prime factors of 814 are 2 x 11 x 37

Prime factors of 642 are 2 x 3 x 107

Prime factors of 715 are 5 x 11 x 13

Prime factors of 624 are 2 x 2 x 2 x 2 x 3 x 13

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

Given numbers are 814, 642, 715, 624

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

Apply this formula for all numbers.

Step1:

LCM(814, 642) = 261294

GCD(814, 642) = ( 814 x 642 ) / 261294

= 814 / 642

= 814

Step2:

LCM(2, 715) = 1430

GCD(2, 715) = ( 2 x 715 ) / 1430

= 2 / 715

= 2

Step3:

LCM(1, 624) = 624

GCD(1, 624) = ( 1 x 624 ) / 624

= 1 / 624

= 1

So, Greatest Common Divisor of 814, 642, 715, 624 is 1
