Given numbers are 558, 402, 445, 447

The list of prime factors of all numbers are

Prime factors of 558 are 2 x 3 x 3 x 31

Prime factors of 402 are 2 x 3 x 67

Prime factors of 445 are 5 x 89

Prime factors of 447 are 3 x 149

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

Given numbers are 558, 402, 445, 447

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

Apply this formula for all numbers.

Step1:

LCM(558, 402) = 37386

GCD(558, 402) = ( 558 x 402 ) / 37386

= 558 / 402

= 558

Step2:

LCM(6, 445) = 2670

GCD(6, 445) = ( 6 x 445 ) / 2670

= 6 / 445

= 6

Step3:

LCM(1, 447) = 447

GCD(1, 447) = ( 1 x 447 ) / 447

= 1 / 447

= 1

So, Greatest Common Divisor of 558, 402, 445, 447 is 1
