Given numbers are 490, 688, 225, 694

The list of prime factors of all numbers are

Prime factors of 490 are 2 x 5 x 7 x 7

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

Prime factors of 225 are 3 x 3 x 5 x 5

Prime factors of 694 are 2 x 347

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

Given numbers are 490, 688, 225, 694

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

Apply this formula for all numbers.

Step1:

LCM(490, 688) = 168560

GCD(490, 688) = ( 490 x 688 ) / 168560

= 490 / 688

= 490

Step2:

LCM(2, 225) = 450

GCD(2, 225) = ( 2 x 225 ) / 450

= 2 / 225

= 2

Step3:

LCM(1, 694) = 694

GCD(1, 694) = ( 1 x 694 ) / 694

= 1 / 694

= 1

So, Greatest Common Divisor of 490, 688, 225, 694 is 1
