Given numbers are 620, 285, 523, 426

The list of prime factors of all numbers are

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 285 are 3 x 5 x 19

Prime factors of 523 are 523

Prime factors of 426 are 2 x 3 x 71

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

Given numbers are 620, 285, 523, 426

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

Apply this formula for all numbers.

Step1:

LCM(620, 285) = 35340

GCD(620, 285) = ( 620 x 285 ) / 35340

= 620 / 285

= 620

Step2:

LCM(5, 523) = 2615

GCD(5, 523) = ( 5 x 523 ) / 2615

= 5 / 523

= 5

Step3:

LCM(1, 426) = 426

GCD(1, 426) = ( 1 x 426 ) / 426

= 1 / 426

= 1

So, Greatest Common Divisor of 620, 285, 523, 426 is 1
