Given numbers are 620, 980, 283, 458

The list of prime factors of all numbers are

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

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

Prime factors of 283 are 283

Prime factors of 458 are 2 x 229

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

Given numbers are 620, 980, 283, 458

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

Apply this formula for all numbers.

Step1:

LCM(620, 980) = 30380

GCD(620, 980) = ( 620 x 980 ) / 30380

= 620 / 980

= 620

Step2:

LCM(20, 283) = 5660

GCD(20, 283) = ( 20 x 283 ) / 5660

= 20 / 283

= 20

Step3:

LCM(1, 458) = 458

GCD(1, 458) = ( 1 x 458 ) / 458

= 1 / 458

= 1

So, Greatest Common Divisor of 620, 980, 283, 458 is 1
