Given numbers are 621, 245, 508

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

Apply this formula for all numbers.

Step1:

LCM(621, 245) = 152145

GCD(621, 245) = ( 621 x 245 ) / 152145

= 621 / 245

= 621

Step2:

LCM(1, 508) = 508

GCD(1, 508) = ( 1 x 508 ) / 508

= 1 / 508

= 1

So, Greatest Common Divisor of 621, 245, 508 is 1
