Given numbers are 840, 657, 445, 659

The list of prime factors of all numbers are

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 657 are 3 x 3 x 73

Prime factors of 445 are 5 x 89

Prime factors of 659 are 659

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

Given numbers are 840, 657, 445, 659

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

Apply this formula for all numbers.

Step1:

LCM(840, 657) = 183960

GCD(840, 657) = ( 840 x 657 ) / 183960

= 840 / 657

= 840

Step2:

LCM(3, 445) = 1335

GCD(3, 445) = ( 3 x 445 ) / 1335

= 3 / 445

= 3

Step3:

LCM(1, 659) = 659

GCD(1, 659) = ( 1 x 659 ) / 659

= 1 / 659

= 1

So, Greatest Common Divisor of 840, 657, 445, 659 is 1
