Given numbers are 254, 438, 639, 373

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

Apply this formula for all numbers.

Step1:

LCM(254, 438) = 55626

GCD(254, 438) = ( 254 x 438 ) / 55626

= 254 / 438

= 254

Step2:

LCM(2, 639) = 1278

GCD(2, 639) = ( 2 x 639 ) / 1278

= 2 / 639

= 2

Step3:

LCM(1, 373) = 373

GCD(1, 373) = ( 1 x 373 ) / 373

= 1 / 373

= 1

So, Greatest Common Divisor of 254, 438, 639, 373 is 1
