Given numbers are 490, 138, 34, 491

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

Apply this formula for all numbers.

Step1:

LCM(490, 138) = 33810

GCD(490, 138) = ( 490 x 138 ) / 33810

= 490 / 138

= 490

Step2:

LCM(2, 34) = 34

GCD(2, 34) = ( 2 x 34 ) / 34

= 2 / 34

= 2

Step3:

LCM(2, 491) = 982

GCD(2, 491) = ( 2 x 491 ) / 982

= 2 / 491

= 2

So, Greatest Common Divisor of 490, 138, 34, 491 is 1
