Given numbers are 361, 121, 129, 447

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

Apply this formula for all numbers.

Step1:

LCM(361, 121) = 43681

GCD(361, 121) = ( 361 x 121 ) / 43681

= 361 / 121

= 361

Step2:

LCM(1, 129) = 129

GCD(1, 129) = ( 1 x 129 ) / 129

= 1 / 129

= 1

Step3:

LCM(1, 447) = 447

GCD(1, 447) = ( 1 x 447 ) / 447

= 1 / 447

= 1

So, Greatest Common Divisor of 361, 121, 129, 447 is 1
