Given numbers are 438, 632, 916, 305

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

Apply this formula for all numbers.

Step1:

LCM(438, 632) = 138408

GCD(438, 632) = ( 438 x 632 ) / 138408

= 438 / 632

= 438

Step2:

LCM(2, 916) = 916

GCD(2, 916) = ( 2 x 916 ) / 916

= 2 / 916

= 2

Step3:

LCM(2, 305) = 610

GCD(2, 305) = ( 2 x 305 ) / 610

= 2 / 305

= 2

So, Greatest Common Divisor of 438, 632, 916, 305 is 1
