Given numbers are 945, 438, 125, 223

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

Apply this formula for all numbers.

Step1:

LCM(945, 438) = 137970

GCD(945, 438) = ( 945 x 438 ) / 137970

= 945 / 438

= 945

Step2:

LCM(3, 125) = 375

GCD(3, 125) = ( 3 x 125 ) / 375

= 3 / 125

= 3

Step3:

LCM(1, 223) = 223

GCD(1, 223) = ( 1 x 223 ) / 223

= 1 / 223

= 1

So, Greatest Common Divisor of 945, 438, 125, 223 is 1
