Given numbers are 438, 199, 323, 428
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(438, 199) = 87162
GCD(438, 199) = ( 438 x 199 ) / 87162
= 438 / 199
= 438
Step2:
LCM(1, 323) = 323
GCD(1, 323) = ( 1 x 323 ) / 323
= 1 / 323
= 1
Step3:
LCM(1, 428) = 428
GCD(1, 428) = ( 1 x 428 ) / 428
= 1 / 428
= 1
So, Greatest Common Divisor of 438, 199, 323, 428 is 1
