Given numbers are 945, 738, 415, 143

The list of prime factors of all numbers are

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 738 are 2 x 3 x 3 x 41

Prime factors of 415 are 5 x 83

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 945, 738, 415, 143

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

Apply this formula for all numbers.

Step1:

LCM(945, 738) = 77490

GCD(945, 738) = ( 945 x 738 ) / 77490

= 945 / 738

= 945

Step2:

LCM(9, 415) = 3735

GCD(9, 415) = ( 9 x 415 ) / 3735

= 9 / 415

= 9

Step3:

LCM(1, 143) = 143

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

= 1 / 143

= 1

So, Greatest Common Divisor of 945, 738, 415, 143 is 1
