Given numbers are 821, 807, 783, 484

The list of prime factors of all numbers are

Prime factors of 821 are 821

Prime factors of 807 are 3 x 269

Prime factors of 783 are 3 x 3 x 3 x 29

Prime factors of 484 are 2 x 2 x 11 x 11

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

Given numbers are 821, 807, 783, 484

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

Apply this formula for all numbers.

Step1:

LCM(821, 807) = 662547

GCD(821, 807) = ( 821 x 807 ) / 662547

= 821 / 807

= 821

Step2:

LCM(1, 783) = 783

GCD(1, 783) = ( 1 x 783 ) / 783

= 1 / 783

= 1

Step3:

LCM(1, 484) = 484

GCD(1, 484) = ( 1 x 484 ) / 484

= 1 / 484

= 1

So, Greatest Common Divisor of 821, 807, 783, 484 is 1
