Given numbers are 642, 445, 411, 886

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 445 are 5 x 89

Prime factors of 411 are 3 x 137

Prime factors of 886 are 2 x 443

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

Given numbers are 642, 445, 411, 886

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

Apply this formula for all numbers.

Step1:

LCM(642, 445) = 285690

GCD(642, 445) = ( 642 x 445 ) / 285690

= 642 / 445

= 642

Step2:

LCM(1, 411) = 411

GCD(1, 411) = ( 1 x 411 ) / 411

= 1 / 411

= 1

Step3:

LCM(1, 886) = 886

GCD(1, 886) = ( 1 x 886 ) / 886

= 1 / 886

= 1

So, Greatest Common Divisor of 642, 445, 411, 886 is 1
