Given numbers are 415, 159, 668, 218

The list of prime factors of all numbers are

Prime factors of 415 are 5 x 83

Prime factors of 159 are 3 x 53

Prime factors of 668 are 2 x 2 x 167

Prime factors of 218 are 2 x 109

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

Given numbers are 415, 159, 668, 218

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

Apply this formula for all numbers.

Step1:

LCM(415, 159) = 65985

GCD(415, 159) = ( 415 x 159 ) / 65985

= 415 / 159

= 415

Step2:

LCM(1, 668) = 668

GCD(1, 668) = ( 1 x 668 ) / 668

= 1 / 668

= 1

Step3:

LCM(1, 218) = 218

GCD(1, 218) = ( 1 x 218 ) / 218

= 1 / 218

= 1

So, Greatest Common Divisor of 415, 159, 668, 218 is 1
