Given numbers are 143, 645, 353, 730

The list of prime factors of all numbers are

Prime factors of 143 are 11 x 13

Prime factors of 645 are 3 x 5 x 43

Prime factors of 353 are 353

Prime factors of 730 are 2 x 5 x 73

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

Given numbers are 143, 645, 353, 730

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

Apply this formula for all numbers.

Step1:

LCM(143, 645) = 92235

GCD(143, 645) = ( 143 x 645 ) / 92235

= 143 / 645

= 143

Step2:

LCM(1, 353) = 353

GCD(1, 353) = ( 1 x 353 ) / 353

= 1 / 353

= 1

Step3:

LCM(1, 730) = 730

GCD(1, 730) = ( 1 x 730 ) / 730

= 1 / 730

= 1

So, Greatest Common Divisor of 143, 645, 353, 730 is 1
