Given numbers are 821, 490, 270, 843

The list of prime factors of all numbers are

Prime factors of 821 are 821

Prime factors of 490 are 2 x 5 x 7 x 7

Prime factors of 270 are 2 x 3 x 3 x 3 x 5

Prime factors of 843 are 3 x 281

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

Given numbers are 821, 490, 270, 843

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

Apply this formula for all numbers.

Step1:

LCM(821, 490) = 402290

GCD(821, 490) = ( 821 x 490 ) / 402290

= 821 / 490

= 821

Step2:

LCM(1, 270) = 270

GCD(1, 270) = ( 1 x 270 ) / 270

= 1 / 270

= 1

Step3:

LCM(1, 843) = 843

GCD(1, 843) = ( 1 x 843 ) / 843

= 1 / 843

= 1

So, Greatest Common Divisor of 821, 490, 270, 843 is 1
