Given numbers are 407, 703, 820, 706

The list of prime factors of all numbers are

Prime factors of 407 are 11 x 37

Prime factors of 703 are 19 x 37

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 706 are 2 x 353

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

Given numbers are 407, 703, 820, 706

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

Apply this formula for all numbers.

Step1:

LCM(407, 703) = 7733

GCD(407, 703) = ( 407 x 703 ) / 7733

= 407 / 703

= 407

Step2:

LCM(37, 820) = 30340

GCD(37, 820) = ( 37 x 820 ) / 30340

= 37 / 820

= 37

Step3:

LCM(1, 706) = 706

GCD(1, 706) = ( 1 x 706 ) / 706

= 1 / 706

= 1

So, Greatest Common Divisor of 407, 703, 820, 706 is 1
