Given numbers are 257, 841, 795, 840

The list of prime factors of all numbers are

Prime factors of 257 are 257

Prime factors of 841 are 29 x 29

Prime factors of 795 are 3 x 5 x 53

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 257, 841, 795, 840

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

Apply this formula for all numbers.

Step1:

LCM(257, 841) = 216137

GCD(257, 841) = ( 257 x 841 ) / 216137

= 257 / 841

= 257

Step2:

LCM(1, 795) = 795

GCD(1, 795) = ( 1 x 795 ) / 795

= 1 / 795

= 1

Step3:

LCM(1, 840) = 840

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

= 1 / 840

= 1

So, Greatest Common Divisor of 257, 841, 795, 840 is 1
