Given numbers are 670, 629, 409, 447

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

Apply this formula for all numbers.

Step1:

LCM(670, 629) = 421430

GCD(670, 629) = ( 670 x 629 ) / 421430

= 670 / 629

= 670

Step2:

LCM(1, 409) = 409

GCD(1, 409) = ( 1 x 409 ) / 409

= 1 / 409

= 1

Step3:

LCM(1, 447) = 447

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

= 1 / 447

= 1

So, Greatest Common Divisor of 670, 629, 409, 447 is 1
