Given numbers are 208, 170, 155, 518

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

Apply this formula for all numbers.

Step1:

LCM(208, 170) = 17680

GCD(208, 170) = ( 208 x 170 ) / 17680

= 208 / 170

= 208

Step2:

LCM(2, 155) = 310

GCD(2, 155) = ( 2 x 155 ) / 310

= 2 / 155

= 2

Step3:

LCM(1, 518) = 518

GCD(1, 518) = ( 1 x 518 ) / 518

= 1 / 518

= 1

So, Greatest Common Divisor of 208, 170, 155, 518 is 1
