Given numbers are 490, 920, 619, 809

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

Apply this formula for all numbers.

Step1:

LCM(490, 920) = 45080

GCD(490, 920) = ( 490 x 920 ) / 45080

= 490 / 920

= 490

Step2:

LCM(10, 619) = 6190

GCD(10, 619) = ( 10 x 619 ) / 6190

= 10 / 619

= 10

Step3:

LCM(1, 809) = 809

GCD(1, 809) = ( 1 x 809 ) / 809

= 1 / 809

= 1

So, Greatest Common Divisor of 490, 920, 619, 809 is 1
