Given numbers are 283, 154, 543, 840

The list of prime factors of all numbers are

Prime factors of 283 are 283

Prime factors of 154 are 2 x 7 x 11

Prime factors of 543 are 3 x 181

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

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

Given numbers are 283, 154, 543, 840

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

Apply this formula for all numbers.

Step1:

LCM(283, 154) = 43582

GCD(283, 154) = ( 283 x 154 ) / 43582

= 283 / 154

= 283

Step2:

LCM(1, 543) = 543

GCD(1, 543) = ( 1 x 543 ) / 543

= 1 / 543

= 1

Step3:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

So, Greatest Common Divisor of 283, 154, 543, 840 is 1
