Given numbers are 445, 309, 537, 674

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

Apply this formula for all numbers.

Step1:

LCM(445, 309) = 137505

GCD(445, 309) = ( 445 x 309 ) / 137505

= 445 / 309

= 445

Step2:

LCM(1, 537) = 537

GCD(1, 537) = ( 1 x 537 ) / 537

= 1 / 537

= 1

Step3:

LCM(1, 674) = 674

GCD(1, 674) = ( 1 x 674 ) / 674

= 1 / 674

= 1

So, Greatest Common Divisor of 445, 309, 537, 674 is 1
