Given numbers are 518, 245, 609, 961

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

Apply this formula for all numbers.

Step1:

LCM(518, 245) = 18130

GCD(518, 245) = ( 518 x 245 ) / 18130

= 518 / 245

= 518

Step2:

LCM(7, 609) = 609

GCD(7, 609) = ( 7 x 609 ) / 609

= 7 / 609

= 7

Step3:

LCM(7, 961) = 6727

GCD(7, 961) = ( 7 x 961 ) / 6727

= 7 / 961

= 7

So, Greatest Common Divisor of 518, 245, 609, 961 is 1
