Given numbers are 424, 425, 128, 673

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

Apply this formula for all numbers.

Step1:

LCM(424, 425) = 180200

GCD(424, 425) = ( 424 x 425 ) / 180200

= 424 / 425

= 424

Step2:

LCM(1, 128) = 128

GCD(1, 128) = ( 1 x 128 ) / 128

= 1 / 128

= 1

Step3:

LCM(1, 673) = 673

GCD(1, 673) = ( 1 x 673 ) / 673

= 1 / 673

= 1

So, Greatest Common Divisor of 424, 425, 128, 673 is 1
