Given numbers are 840, 130, 505, 669

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 130 are 2 x 5 x 13

Prime factors of 505 are 5 x 101

Prime factors of 669 are 3 x 223

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

Given numbers are 840, 130, 505, 669

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

Apply this formula for all numbers.

Step1:

LCM(840, 130) = 10920

GCD(840, 130) = ( 840 x 130 ) / 10920

= 840 / 130

= 840

Step2:

LCM(10, 505) = 1010

GCD(10, 505) = ( 10 x 505 ) / 1010

= 10 / 505

= 10

Step3:

LCM(5, 669) = 3345

GCD(5, 669) = ( 5 x 669 ) / 3345

= 5 / 669

= 5

So, Greatest Common Divisor of 840, 130, 505, 669 is 1
