Given numbers are 621, 945, 586, 505

The list of prime factors of all numbers are

Prime factors of 621 are 3 x 3 x 3 x 23

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

Prime factors of 586 are 2 x 293

Prime factors of 505 are 5 x 101

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

Given numbers are 621, 945, 586, 505

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

Apply this formula for all numbers.

Step1:

LCM(621, 945) = 21735

GCD(621, 945) = ( 621 x 945 ) / 21735

= 621 / 945

= 621

Step2:

LCM(27, 586) = 15822

GCD(27, 586) = ( 27 x 586 ) / 15822

= 27 / 586

= 27

Step3:

LCM(1, 505) = 505

GCD(1, 505) = ( 1 x 505 ) / 505

= 1 / 505

= 1

So, Greatest Common Divisor of 621, 945, 586, 505 is 1
