Given numbers are 557, 518, 245, 165

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

Apply this formula for all numbers.

Step1:

LCM(557, 518) = 288526

GCD(557, 518) = ( 557 x 518 ) / 288526

= 557 / 518

= 557

Step2:

LCM(1, 245) = 245

GCD(1, 245) = ( 1 x 245 ) / 245

= 1 / 245

= 1

Step3:

LCM(1, 165) = 165

GCD(1, 165) = ( 1 x 165 ) / 165

= 1 / 165

= 1

So, Greatest Common Divisor of 557, 518, 245, 165 is 1
