Given numbers are 630, 245, 343

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

Apply this formula for all numbers.

Step1:

LCM(630, 245) = 4410

GCD(630, 245) = ( 630 x 245 ) / 4410

= 630 / 245

= 630

Step2:

LCM(35, 343) = 1715

GCD(35, 343) = ( 35 x 343 ) / 1715

= 35 / 343

= 35

So, Greatest Common Divisor of 630, 245, 343 is 7
