Given numbers are 684, 820, 434, 531

The list of prime factors of all numbers are

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 434 are 2 x 7 x 31

Prime factors of 531 are 3 x 3 x 59

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

Given numbers are 684, 820, 434, 531

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

Apply this formula for all numbers.

Step1:

LCM(684, 820) = 140220

GCD(684, 820) = ( 684 x 820 ) / 140220

= 684 / 820

= 684

Step2:

LCM(4, 434) = 868

GCD(4, 434) = ( 4 x 434 ) / 868

= 4 / 434

= 4

Step3:

LCM(2, 531) = 1062

GCD(2, 531) = ( 2 x 531 ) / 1062

= 2 / 531

= 2

So, Greatest Common Divisor of 684, 820, 434, 531 is 1
