Given numbers are 145, 408, 832, 668

The list of prime factors of all numbers are

Prime factors of 145 are 5 x 29

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

Prime factors of 832 are 2 x 2 x 2 x 2 x 2 x 2 x 13

Prime factors of 668 are 2 x 2 x 167

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

Given numbers are 145, 408, 832, 668

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

Apply this formula for all numbers.

Step1:

LCM(145, 408) = 59160

GCD(145, 408) = ( 145 x 408 ) / 59160

= 145 / 408

= 145

Step2:

LCM(1, 832) = 832

GCD(1, 832) = ( 1 x 832 ) / 832

= 1 / 832

= 1

Step3:

LCM(1, 668) = 668

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

= 1 / 668

= 1

So, Greatest Common Divisor of 145, 408, 832, 668 is 1
