Given numbers are 931, 812, 399, 693

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

Apply this formula for all numbers.

Step1:

LCM(931, 812) = 107996

GCD(931, 812) = ( 931 x 812 ) / 107996

= 931 / 812

= 931

Step2:

LCM(7, 399) = 399

GCD(7, 399) = ( 7 x 399 ) / 399

= 7 / 399

= 7

Step3:

LCM(7, 693) = 693

GCD(7, 693) = ( 7 x 693 ) / 693

= 7 / 693

= 7

So, Greatest Common Divisor of 931, 812, 399, 693 is 7
