Given numbers are 415, 249, 642

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

Apply this formula for all numbers.

Step1:

LCM(415, 249) = 1245

GCD(415, 249) = ( 415 x 249 ) / 1245

= 415 / 249

= 415

Step2:

LCM(83, 642) = 53286

GCD(83, 642) = ( 83 x 642 ) / 53286

= 83 / 642

= 83

So, Greatest Common Divisor of 415, 249, 642 is 1
