Given numbers are 130, 253, 146, 820

The list of prime factors of all numbers are

Prime factors of 130 are 2 x 5 x 13

Prime factors of 253 are 11 x 23

Prime factors of 146 are 2 x 73

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

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

Given numbers are 130, 253, 146, 820

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

Apply this formula for all numbers.

Step1:

LCM(130, 253) = 32890

GCD(130, 253) = ( 130 x 253 ) / 32890

= 130 / 253

= 130

Step2:

LCM(1, 146) = 146

GCD(1, 146) = ( 1 x 146 ) / 146

= 1 / 146

= 1

Step3:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

So, Greatest Common Divisor of 130, 253, 146, 820 is 1
