Given numbers are 815, 820, 153, 548

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

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

Prime factors of 153 are 3 x 3 x 17

Prime factors of 548 are 2 x 2 x 137

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

Given numbers are 815, 820, 153, 548

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

Apply this formula for all numbers.

Step1:

LCM(815, 820) = 133660

GCD(815, 820) = ( 815 x 820 ) / 133660

= 815 / 820

= 815

Step2:

LCM(5, 153) = 765

GCD(5, 153) = ( 5 x 153 ) / 765

= 5 / 153

= 5

Step3:

LCM(1, 548) = 548

GCD(1, 548) = ( 1 x 548 ) / 548

= 1 / 548

= 1

So, Greatest Common Divisor of 815, 820, 153, 548 is 1
