Given numbers are 682, 642, 447, 784

The list of prime factors of all numbers are

Prime factors of 682 are 2 x 11 x 31

Prime factors of 642 are 2 x 3 x 107

Prime factors of 447 are 3 x 149

Prime factors of 784 are 2 x 2 x 2 x 2 x 7 x 7

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

Given numbers are 682, 642, 447, 784

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

Apply this formula for all numbers.

Step1:

LCM(682, 642) = 218922

GCD(682, 642) = ( 682 x 642 ) / 218922

= 682 / 642

= 682

Step2:

LCM(2, 447) = 894

GCD(2, 447) = ( 2 x 447 ) / 894

= 2 / 447

= 2

Step3:

LCM(1, 784) = 784

GCD(1, 784) = ( 1 x 784 ) / 784

= 1 / 784

= 1

So, Greatest Common Divisor of 682, 642, 447, 784 is 1
