Given numbers are 254, 940, 783, 638

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

Apply this formula for all numbers.

Step1:

LCM(254, 940) = 119380

GCD(254, 940) = ( 254 x 940 ) / 119380

= 254 / 940

= 254

Step2:

LCM(2, 783) = 1566

GCD(2, 783) = ( 2 x 783 ) / 1566

= 2 / 783

= 2

Step3:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

So, Greatest Common Divisor of 254, 940, 783, 638 is 1
