Given numbers are 945, 312, 28, 984

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

Apply this formula for all numbers.

Step1:

LCM(945, 312) = 98280

GCD(945, 312) = ( 945 x 312 ) / 98280

= 945 / 312

= 945

Step2:

LCM(3, 28) = 84

GCD(3, 28) = ( 3 x 28 ) / 84

= 3 / 28

= 3

Step3:

LCM(1, 984) = 984

GCD(1, 984) = ( 1 x 984 ) / 984

= 1 / 984

= 1

So, Greatest Common Divisor of 945, 312, 28, 984 is 1
