Given numbers are 847, 931, 389, 825

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

Apply this formula for all numbers.

Step1:

LCM(847, 931) = 112651

GCD(847, 931) = ( 847 x 931 ) / 112651

= 847 / 931

= 847

Step2:

LCM(7, 389) = 2723

GCD(7, 389) = ( 7 x 389 ) / 2723

= 7 / 389

= 7

Step3:

LCM(1, 825) = 825

GCD(1, 825) = ( 1 x 825 ) / 825

= 1 / 825

= 1

So, Greatest Common Divisor of 847, 931, 389, 825 is 1
