Given numbers are 690, 146, 424, 117

The list of prime factors of all numbers are

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 146 are 2 x 73

Prime factors of 424 are 2 x 2 x 2 x 53

Prime factors of 117 are 3 x 3 x 13

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

Given numbers are 690, 146, 424, 117

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

Apply this formula for all numbers.

Step1:

LCM(690, 146) = 50370

GCD(690, 146) = ( 690 x 146 ) / 50370

= 690 / 146

= 690

Step2:

LCM(2, 424) = 424

GCD(2, 424) = ( 2 x 424 ) / 424

= 2 / 424

= 2

Step3:

LCM(2, 117) = 234

GCD(2, 117) = ( 2 x 117 ) / 234

= 2 / 117

= 2

So, Greatest Common Divisor of 690, 146, 424, 117 is 1
