Given numbers are 315, 445, 245, 640

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

Apply this formula for all numbers.

Step1:

LCM(315, 445) = 28035

GCD(315, 445) = ( 315 x 445 ) / 28035

= 315 / 445

= 315

Step2:

LCM(5, 245) = 245

GCD(5, 245) = ( 5 x 245 ) / 245

= 5 / 245

= 5

Step3:

LCM(5, 640) = 640

GCD(5, 640) = ( 5 x 640 ) / 640

= 5 / 640

= 5

So, Greatest Common Divisor of 315, 445, 245, 640 is 5
