Given numbers are 945, 447, 20

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

Apply this formula for all numbers.

Step1:

LCM(945, 447) = 140805

GCD(945, 447) = ( 945 x 447 ) / 140805

= 945 / 447

= 945

Step2:

LCM(3, 20) = 60

GCD(3, 20) = ( 3 x 20 ) / 60

= 3 / 20

= 3

So, Greatest Common Divisor of 945, 447, 20 is 1
