Given numbers are 847, 855, 931, 449

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

Apply this formula for all numbers.

Step1:

LCM(847, 855) = 724185

GCD(847, 855) = ( 847 x 855 ) / 724185

= 847 / 855

= 847

Step2:

LCM(1, 931) = 931

GCD(1, 931) = ( 1 x 931 ) / 931

= 1 / 931

= 1

Step3:

LCM(1, 449) = 449

GCD(1, 449) = ( 1 x 449 ) / 449

= 1 / 449

= 1

So, Greatest Common Divisor of 847, 855, 931, 449 is 1
