Given numbers are 945, 306, 480, 879

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

Apply this formula for all numbers.

Step1:

LCM(945, 306) = 32130

GCD(945, 306) = ( 945 x 306 ) / 32130

= 945 / 306

= 945

Step2:

LCM(9, 480) = 1440

GCD(9, 480) = ( 9 x 480 ) / 1440

= 9 / 480

= 9

Step3:

LCM(3, 879) = 879

GCD(3, 879) = ( 3 x 879 ) / 879

= 3 / 879

= 3

So, Greatest Common Divisor of 945, 306, 480, 879 is 3
