Given numbers are 281, 840, 421, 771

The list of prime factors of all numbers are

Prime factors of 281 are 281

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

Prime factors of 421 are 421

Prime factors of 771 are 3 x 257

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

Given numbers are 281, 840, 421, 771

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

Apply this formula for all numbers.

Step1:

LCM(281, 840) = 236040

GCD(281, 840) = ( 281 x 840 ) / 236040

= 281 / 840

= 281

Step2:

LCM(1, 421) = 421

GCD(1, 421) = ( 1 x 421 ) / 421

= 1 / 421

= 1

Step3:

LCM(1, 771) = 771

GCD(1, 771) = ( 1 x 771 ) / 771

= 1 / 771

= 1

So, Greatest Common Divisor of 281, 840, 421, 771 is 1
