Given numbers are 183, 391, 464, 438
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(183, 391) = 71553
GCD(183, 391) = ( 183 x 391 ) / 71553
= 183 / 391
= 183
Step2:
LCM(1, 464) = 464
GCD(1, 464) = ( 1 x 464 ) / 464
= 1 / 464
= 1
Step3:
LCM(1, 438) = 438
GCD(1, 438) = ( 1 x 438 ) / 438
= 1 / 438
= 1
So, Greatest Common Divisor of 183, 391, 464, 438 is 1
