Given numbers are 823, 640, 688, 973

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

Apply this formula for all numbers.

Step1:

LCM(823, 640) = 526720

GCD(823, 640) = ( 823 x 640 ) / 526720

= 823 / 640

= 823

Step2:

LCM(1, 688) = 688

GCD(1, 688) = ( 1 x 688 ) / 688

= 1 / 688

= 1

Step3:

LCM(1, 973) = 973

GCD(1, 973) = ( 1 x 973 ) / 973

= 1 / 973

= 1

So, Greatest Common Divisor of 823, 640, 688, 973 is 1
