Given numbers are 225, 381, 113, 642

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

Apply this formula for all numbers.

Step1:

LCM(225, 381) = 28575

GCD(225, 381) = ( 225 x 381 ) / 28575

= 225 / 381

= 225

Step2:

LCM(3, 113) = 339

GCD(3, 113) = ( 3 x 113 ) / 339

= 3 / 113

= 3

Step3:

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

= 1 / 642

= 1

So, Greatest Common Divisor of 225, 381, 113, 642 is 1
