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

Given numbers are 485, 645, 890, 487

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

Apply this formula for all numbers.

Step1:

LCM(485, 645) = 62565

GCD(485, 645) = ( 485 x 645 ) / 62565

= 485 / 645

= 485

Step2:

LCM(5, 890) = 890

GCD(5, 890) = ( 5 x 890 ) / 890

= 5 / 890

= 5

Step3:

LCM(5, 487) = 2435

GCD(5, 487) = ( 5 x 487 ) / 2435

= 5 / 487

= 5

So, Greatest Common Divisor of 485, 645, 890, 487 is 1
