Given numbers are 168, 143, 408, 615

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 143 are 11 x 13

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 615 are 3 x 5 x 41

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

Given numbers are 168, 143, 408, 615

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

Apply this formula for all numbers.

Step1:

LCM(168, 143) = 24024

GCD(168, 143) = ( 168 x 143 ) / 24024

= 168 / 143

= 168

Step2:

LCM(1, 408) = 408

GCD(1, 408) = ( 1 x 408 ) / 408

= 1 / 408

= 1

Step3:

LCM(1, 615) = 615

GCD(1, 615) = ( 1 x 615 ) / 615

= 1 / 615

= 1

So, Greatest Common Divisor of 168, 143, 408, 615 is 1
