Given numbers are 727, 438, 426, 394
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(727, 438) = 318426
GCD(727, 438) = ( 727 x 438 ) / 318426
= 727 / 438
= 727
Step2:
LCM(1, 426) = 426
GCD(1, 426) = ( 1 x 426 ) / 426
= 1 / 426
= 1
Step3:
LCM(1, 394) = 394
GCD(1, 394) = ( 1 x 394 ) / 394
= 1 / 394
= 1
So, Greatest Common Divisor of 727, 438, 426, 394 is 1
