Given numbers are 858, 160, 545, 457

The list of prime factors of all numbers are

Prime factors of 858 are 2 x 3 x 11 x 13

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

Prime factors of 545 are 5 x 109

Prime factors of 457 are 457

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

Given numbers are 858, 160, 545, 457

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

Apply this formula for all numbers.

Step1:

LCM(858, 160) = 68640

GCD(858, 160) = ( 858 x 160 ) / 68640

= 858 / 160

= 858

Step2:

LCM(2, 545) = 1090

GCD(2, 545) = ( 2 x 545 ) / 1090

= 2 / 545

= 2

Step3:

LCM(1, 457) = 457

GCD(1, 457) = ( 1 x 457 ) / 457

= 1 / 457

= 1

So, Greatest Common Divisor of 858, 160, 545, 457 is 1
