Given numbers are 638, 815, 325, 574

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

Apply this formula for all numbers.

Step1:

LCM(638, 815) = 519970

GCD(638, 815) = ( 638 x 815 ) / 519970

= 638 / 815

= 638

Step2:

LCM(1, 325) = 325

GCD(1, 325) = ( 1 x 325 ) / 325

= 1 / 325

= 1

Step3:

LCM(1, 574) = 574

GCD(1, 574) = ( 1 x 574 ) / 574

= 1 / 574

= 1

So, Greatest Common Divisor of 638, 815, 325, 574 is 1
