Given numbers are 490, 835, 698, 861

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

Apply this formula for all numbers.

Step1:

LCM(490, 835) = 81830

GCD(490, 835) = ( 490 x 835 ) / 81830

= 490 / 835

= 490

Step2:

LCM(5, 698) = 3490

GCD(5, 698) = ( 5 x 698 ) / 3490

= 5 / 698

= 5

Step3:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

So, Greatest Common Divisor of 490, 835, 698, 861 is 1
