Given numbers are 665, 411, 160, 455

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

Prime factors of 411 are 3 x 137

Prime factors of 160 are 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 455 are 5 x 7 x 13

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

Given numbers are 665, 411, 160, 455

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

Apply this formula for all numbers.

Step1:

LCM(665, 411) = 273315

GCD(665, 411) = ( 665 x 411 ) / 273315

= 665 / 411

= 665

Step2:

LCM(1, 160) = 160

GCD(1, 160) = ( 1 x 160 ) / 160

= 1 / 160

= 1

Step3:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

So, Greatest Common Divisor of 665, 411, 160, 455 is 1
