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

Apply this formula for all numbers.

Step1:

LCM(945, 375) = 23625

GCD(945, 375) = ( 945 x 375 ) / 23625

= 945 / 375

= 945

Step2:

LCM(15, 243) = 1215

GCD(15, 243) = ( 15 x 243 ) / 1215

= 15 / 243

= 15

Step3:

LCM(3, 870) = 870

GCD(3, 870) = ( 3 x 870 ) / 870

= 3 / 870

= 3

So, Greatest Common Divisor of 945, 375, 243, 870 is 3
