Given numbers are 805, 414, 668, 105

The list of prime factors of all numbers are

Prime factors of 805 are 5 x 7 x 23

Prime factors of 414 are 2 x 3 x 3 x 23

Prime factors of 668 are 2 x 2 x 167

Prime factors of 105 are 3 x 5 x 7

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

Given numbers are 805, 414, 668, 105

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

Apply this formula for all numbers.

Step1:

LCM(805, 414) = 14490

GCD(805, 414) = ( 805 x 414 ) / 14490

= 805 / 414

= 805

Step2:

LCM(23, 668) = 15364

GCD(23, 668) = ( 23 x 668 ) / 15364

= 23 / 668

= 23

Step3:

LCM(1, 105) = 105

GCD(1, 105) = ( 1 x 105 ) / 105

= 1 / 105

= 1

So, Greatest Common Divisor of 805, 414, 668, 105 is 1
