Given numbers are 620, 662, 522, 445

The list of prime factors of all numbers are

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 662 are 2 x 331

Prime factors of 522 are 2 x 3 x 3 x 29

Prime factors of 445 are 5 x 89

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

Given numbers are 620, 662, 522, 445

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

Apply this formula for all numbers.

Step1:

LCM(620, 662) = 205220

GCD(620, 662) = ( 620 x 662 ) / 205220

= 620 / 662

= 620

Step2:

LCM(2, 522) = 522

GCD(2, 522) = ( 2 x 522 ) / 522

= 2 / 522

= 2

Step3:

LCM(2, 445) = 890

GCD(2, 445) = ( 2 x 445 ) / 890

= 2 / 445

= 2

So, Greatest Common Divisor of 620, 662, 522, 445 is 1
