Given numbers are 850, 688, 638, 247

The list of prime factors of all numbers are

Prime factors of 850 are 2 x 5 x 5 x 17

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

Prime factors of 638 are 2 x 11 x 29

Prime factors of 247 are 13 x 19

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

Given numbers are 850, 688, 638, 247

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

Apply this formula for all numbers.

Step1:

LCM(850, 688) = 292400

GCD(850, 688) = ( 850 x 688 ) / 292400

= 850 / 688

= 850

Step2:

LCM(2, 638) = 638

GCD(2, 638) = ( 2 x 638 ) / 638

= 2 / 638

= 2

Step3:

LCM(2, 247) = 494

GCD(2, 247) = ( 2 x 247 ) / 494

= 2 / 247

= 2

So, Greatest Common Divisor of 850, 688, 638, 247 is 1
