Given numbers are 434, 511, 721, 821

The list of prime factors of all numbers are

Prime factors of 434 are 2 x 7 x 31

Prime factors of 511 are 7 x 73

Prime factors of 721 are 7 x 103

Prime factors of 821 are 821

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

Given numbers are 434, 511, 721, 821

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

Apply this formula for all numbers.

Step1:

LCM(434, 511) = 31682

GCD(434, 511) = ( 434 x 511 ) / 31682

= 434 / 511

= 434

Step2:

LCM(7, 721) = 721

GCD(7, 721) = ( 7 x 721 ) / 721

= 7 / 721

= 7

Step3:

LCM(7, 821) = 5747

GCD(7, 821) = ( 7 x 821 ) / 5747

= 7 / 821

= 7

So, Greatest Common Divisor of 434, 511, 721, 821 is 1
