Given numbers are 756, 285, 623, 143

The list of prime factors of all numbers are

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

Prime factors of 285 are 3 x 5 x 19

Prime factors of 623 are 7 x 89

Prime factors of 143 are 11 x 13

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

Given numbers are 756, 285, 623, 143

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

Apply this formula for all numbers.

Step1:

LCM(756, 285) = 71820

GCD(756, 285) = ( 756 x 285 ) / 71820

= 756 / 285

= 756

Step2:

LCM(3, 623) = 1869

GCD(3, 623) = ( 3 x 623 ) / 1869

= 3 / 623

= 3

Step3:

LCM(1, 143) = 143

GCD(1, 143) = ( 1 x 143 ) / 143

= 1 / 143

= 1

So, Greatest Common Divisor of 756, 285, 623, 143 is 1
