Given numbers are 490, 470, 805, 679

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

Apply this formula for all numbers.

Step1:

LCM(490, 470) = 23030

GCD(490, 470) = ( 490 x 470 ) / 23030

= 490 / 470

= 490

Step2:

LCM(10, 805) = 1610

GCD(10, 805) = ( 10 x 805 ) / 1610

= 10 / 805

= 10

Step3:

LCM(5, 679) = 3395

GCD(5, 679) = ( 5 x 679 ) / 3395

= 5 / 679

= 5

So, Greatest Common Divisor of 490, 470, 805, 679 is 1
