Given numbers are 833, 644, 378, 945

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

Apply this formula for all numbers.

Step1:

LCM(833, 644) = 76636

GCD(833, 644) = ( 833 x 644 ) / 76636

= 833 / 644

= 833

Step2:

LCM(7, 378) = 378

GCD(7, 378) = ( 7 x 378 ) / 378

= 7 / 378

= 7

Step3:

LCM(7, 945) = 945

GCD(7, 945) = ( 7 x 945 ) / 945

= 7 / 945

= 7

So, Greatest Common Divisor of 833, 644, 378, 945 is 7
