Given numbers are 820, 730, 706, 515

The list of prime factors of all numbers are

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

Prime factors of 730 are 2 x 5 x 73

Prime factors of 706 are 2 x 353

Prime factors of 515 are 5 x 103

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

Given numbers are 820, 730, 706, 515

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

Apply this formula for all numbers.

Step1:

LCM(820, 730) = 59860

GCD(820, 730) = ( 820 x 730 ) / 59860

= 820 / 730

= 820

Step2:

LCM(10, 706) = 3530

GCD(10, 706) = ( 10 x 706 ) / 3530

= 10 / 706

= 10

Step3:

LCM(2, 515) = 1030

GCD(2, 515) = ( 2 x 515 ) / 1030

= 2 / 515

= 2

So, Greatest Common Divisor of 820, 730, 706, 515 is 1
