Given numbers are 210, 470, 245

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

Apply this formula for all numbers.

Step1:

LCM(210, 470) = 9870

GCD(210, 470) = ( 210 x 470 ) / 9870

= 210 / 470

= 210

Step2:

LCM(10, 245) = 490

GCD(10, 245) = ( 10 x 245 ) / 490

= 10 / 245

= 10

So, Greatest Common Divisor of 210, 470, 245 is 5
