Given numbers are 413, 685, 705, 681

The list of prime factors of all numbers are

Prime factors of 413 are 7 x 59

Prime factors of 685 are 5 x 137

Prime factors of 705 are 3 x 5 x 47

Prime factors of 681 are 3 x 227

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

Given numbers are 413, 685, 705, 681

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

Apply this formula for all numbers.

Step1:

LCM(413, 685) = 282905

GCD(413, 685) = ( 413 x 685 ) / 282905

= 413 / 685

= 413

Step2:

LCM(1, 705) = 705

GCD(1, 705) = ( 1 x 705 ) / 705

= 1 / 705

= 1

Step3:

LCM(1, 681) = 681

GCD(1, 681) = ( 1 x 681 ) / 681

= 1 / 681

= 1

So, Greatest Common Divisor of 413, 685, 705, 681 is 1
