Given numbers are 687, 143, 918, 160

The list of prime factors of all numbers are

Prime factors of 687 are 3 x 229

Prime factors of 143 are 11 x 13

Prime factors of 918 are 2 x 3 x 3 x 3 x 17

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

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

Given numbers are 687, 143, 918, 160

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

Apply this formula for all numbers.

Step1:

LCM(687, 143) = 98241

GCD(687, 143) = ( 687 x 143 ) / 98241

= 687 / 143

= 687

Step2:

LCM(1, 918) = 918

GCD(1, 918) = ( 1 x 918 ) / 918

= 1 / 918

= 1

Step3:

LCM(1, 160) = 160

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

= 1 / 160

= 1

So, Greatest Common Divisor of 687, 143, 918, 160 is 1
