Given numbers are 298, 423, 145, 671

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

Apply this formula for all numbers.

Step1:

LCM(298, 423) = 126054

GCD(298, 423) = ( 298 x 423 ) / 126054

= 298 / 423

= 298

Step2:

LCM(1, 145) = 145

GCD(1, 145) = ( 1 x 145 ) / 145

= 1 / 145

= 1

Step3:

LCM(1, 671) = 671

GCD(1, 671) = ( 1 x 671 ) / 671

= 1 / 671

= 1

So, Greatest Common Divisor of 298, 423, 145, 671 is 1
