Given numbers are 447, 705, 642, 237

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

Apply this formula for all numbers.

Step1:

LCM(447, 705) = 105045

GCD(447, 705) = ( 447 x 705 ) / 105045

= 447 / 705

= 447

Step2:

LCM(3, 642) = 642

GCD(3, 642) = ( 3 x 642 ) / 642

= 3 / 642

= 3

Step3:

LCM(3, 237) = 237

GCD(3, 237) = ( 3 x 237 ) / 237

= 3 / 237

= 3

So, Greatest Common Divisor of 447, 705, 642, 237 is 3
