Given numbers are 517, 220, 121, 109

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

Apply this formula for all numbers.

Step1:

LCM(517, 220) = 10340

GCD(517, 220) = ( 517 x 220 ) / 10340

= 517 / 220

= 517

Step2:

LCM(11, 121) = 121

GCD(11, 121) = ( 11 x 121 ) / 121

= 11 / 121

= 11

Step3:

LCM(11, 109) = 1199

GCD(11, 109) = ( 11 x 109 ) / 1199

= 11 / 109

= 11

So, Greatest Common Divisor of 517, 220, 121, 109 is 1
