Given numbers are 210, 130, 496, 438

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

Apply this formula for all numbers.

Step1:

LCM(210, 130) = 2730

GCD(210, 130) = ( 210 x 130 ) / 2730

= 210 / 130

= 210

Step2:

LCM(10, 496) = 2480

GCD(10, 496) = ( 10 x 496 ) / 2480

= 10 / 496

= 10

Step3:

LCM(2, 438) = 438

GCD(2, 438) = ( 2 x 438 ) / 438

= 2 / 438

= 2

So, Greatest Common Divisor of 210, 130, 496, 438 is 2
