Given numbers are 145, 520, 435, 442

The list of prime factors of all numbers are

Prime factors of 145 are 5 x 29

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 435 are 3 x 5 x 29

Prime factors of 442 are 2 x 13 x 17

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

Given numbers are 145, 520, 435, 442

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

Apply this formula for all numbers.

Step1:

LCM(145, 520) = 15080

GCD(145, 520) = ( 145 x 520 ) / 15080

= 145 / 520

= 145

Step2:

LCM(5, 435) = 435

GCD(5, 435) = ( 5 x 435 ) / 435

= 5 / 435

= 5

Step3:

LCM(5, 442) = 2210

GCD(5, 442) = ( 5 x 442 ) / 2210

= 5 / 442

= 5

So, Greatest Common Divisor of 145, 520, 435, 442 is 1
