Given numbers are 168, 553, 680, 435

The list of prime factors of all numbers are

Prime factors of 168 are 2 x 2 x 2 x 3 x 7

Prime factors of 553 are 7 x 79

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 435 are 3 x 5 x 29

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

Given numbers are 168, 553, 680, 435

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

Apply this formula for all numbers.

Step1:

LCM(168, 553) = 13272

GCD(168, 553) = ( 168 x 553 ) / 13272

= 168 / 553

= 168

Step2:

LCM(7, 680) = 4760

GCD(7, 680) = ( 7 x 680 ) / 4760

= 7 / 680

= 7

Step3:

LCM(1, 435) = 435

GCD(1, 435) = ( 1 x 435 ) / 435

= 1 / 435

= 1

So, Greatest Common Divisor of 168, 553, 680, 435 is 1
