Given numbers are 397, 445, 857, 847

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

Apply this formula for all numbers.

Step1:

LCM(397, 445) = 176665

GCD(397, 445) = ( 397 x 445 ) / 176665

= 397 / 445

= 397

Step2:

LCM(1, 857) = 857

GCD(1, 857) = ( 1 x 857 ) / 857

= 1 / 857

= 1

Step3:

LCM(1, 847) = 847

GCD(1, 847) = ( 1 x 847 ) / 847

= 1 / 847

= 1

So, Greatest Common Divisor of 397, 445, 857, 847 is 1
