Given numbers are 449, 670, 405, 766

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

Apply this formula for all numbers.

Step1:

LCM(449, 670) = 300830

GCD(449, 670) = ( 449 x 670 ) / 300830

= 449 / 670

= 449

Step2:

LCM(1, 405) = 405

GCD(1, 405) = ( 1 x 405 ) / 405

= 1 / 405

= 1

Step3:

LCM(1, 766) = 766

GCD(1, 766) = ( 1 x 766 ) / 766

= 1 / 766

= 1

So, Greatest Common Divisor of 449, 670, 405, 766 is 1
