Given numbers are 130, 940, 452, 638

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

Apply this formula for all numbers.

Step1:

LCM(130, 940) = 12220

GCD(130, 940) = ( 130 x 940 ) / 12220

= 130 / 940

= 130

Step2:

LCM(10, 452) = 2260

GCD(10, 452) = ( 10 x 452 ) / 2260

= 10 / 452

= 10

Step3:

LCM(2, 638) = 638

GCD(2, 638) = ( 2 x 638 ) / 638

= 2 / 638

= 2

So, Greatest Common Divisor of 130, 940, 452, 638 is 2
