Given numbers are 569, 245, 555, 390

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

Apply this formula for all numbers.

Step1:

LCM(569, 245) = 139405

GCD(569, 245) = ( 569 x 245 ) / 139405

= 569 / 245

= 569

Step2:

LCM(1, 555) = 555

GCD(1, 555) = ( 1 x 555 ) / 555

= 1 / 555

= 1

Step3:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

So, Greatest Common Divisor of 569, 245, 555, 390 is 1
