Given numbers are 430, 196, 27, 490

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

Apply this formula for all numbers.

Step1:

LCM(430, 196) = 42140

GCD(430, 196) = ( 430 x 196 ) / 42140

= 430 / 196

= 430

Step2:

LCM(2, 27) = 54

GCD(2, 27) = ( 2 x 27 ) / 54

= 2 / 27

= 2

Step3:

LCM(1, 490) = 490

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

= 1 / 490

= 1

So, Greatest Common Divisor of 430, 196, 27, 490 is 1
