Given numbers are 655, 463, 647, 447

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

Apply this formula for all numbers.

Step1:

LCM(655, 463) = 303265

GCD(655, 463) = ( 655 x 463 ) / 303265

= 655 / 463

= 655

Step2:

LCM(1, 647) = 647

GCD(1, 647) = ( 1 x 647 ) / 647

= 1 / 647

= 1

Step3:

LCM(1, 447) = 447

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

= 1 / 447

= 1

So, Greatest Common Divisor of 655, 463, 647, 447 is 1
