Given numbers are 638, 968, 945, 230

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

Apply this formula for all numbers.

Step1:

LCM(638, 968) = 28072

GCD(638, 968) = ( 638 x 968 ) / 28072

= 638 / 968

= 638

Step2:

LCM(22, 945) = 20790

GCD(22, 945) = ( 22 x 945 ) / 20790

= 22 / 945

= 22

Step3:

LCM(1, 230) = 230

GCD(1, 230) = ( 1 x 230 ) / 230

= 1 / 230

= 1

So, Greatest Common Divisor of 638, 968, 945, 230 is 1
