Given numbers are 109, 142, 490

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

Apply this formula for all numbers.

Step1:

LCM(109, 142) = 15478

GCD(109, 142) = ( 109 x 142 ) / 15478

= 109 / 142

= 109

Step2:

LCM(1, 490) = 490

GCD(1, 490) = ( 1 x 490 ) / 490

= 1 / 490

= 1

So, Greatest Common Divisor of 109, 142, 490 is 1
