Given numbers are 638, 919, 25, 223

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

Apply this formula for all numbers.

Step1:

LCM(638, 919) = 586322

GCD(638, 919) = ( 638 x 919 ) / 586322

= 638 / 919

= 638

Step2:

LCM(1, 25) = 25

GCD(1, 25) = ( 1 x 25 ) / 25

= 1 / 25

= 1

Step3:

LCM(1, 223) = 223

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

= 1 / 223

= 1

So, Greatest Common Divisor of 638, 919, 25, 223 is 1
