Given numbers are 142, 432, 815, 545

The list of prime factors of all numbers are

Prime factors of 142 are 2 x 71

Prime factors of 432 are 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 815 are 5 x 163

Prime factors of 545 are 5 x 109

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

Given numbers are 142, 432, 815, 545

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

Apply this formula for all numbers.

Step1:

LCM(142, 432) = 30672

GCD(142, 432) = ( 142 x 432 ) / 30672

= 142 / 432

= 142

Step2:

LCM(2, 815) = 1630

GCD(2, 815) = ( 2 x 815 ) / 1630

= 2 / 815

= 2

Step3:

LCM(1, 545) = 545

GCD(1, 545) = ( 1 x 545 ) / 545

= 1 / 545

= 1

So, Greatest Common Divisor of 142, 432, 815, 545 is 1
