Given numbers are 438, 130, 193, 976

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

Apply this formula for all numbers.

Step1:

LCM(438, 130) = 28470

GCD(438, 130) = ( 438 x 130 ) / 28470

= 438 / 130

= 438

Step2:

LCM(2, 193) = 386

GCD(2, 193) = ( 2 x 193 ) / 386

= 2 / 193

= 2

Step3:

LCM(1, 976) = 976

GCD(1, 976) = ( 1 x 976 ) / 976

= 1 / 976

= 1

So, Greatest Common Divisor of 438, 130, 193, 976 is 1
