Given numbers are 905, 129, 387, 443
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(905, 129) = 116745
GCD(905, 129) = ( 905 x 129 ) / 116745
= 905 / 129
= 905
Step2:
LCM(1, 387) = 387
GCD(1, 387) = ( 1 x 387 ) / 387
= 1 / 387
= 1
Step3:
LCM(1, 443) = 443
GCD(1, 443) = ( 1 x 443 ) / 443
= 1 / 443
= 1
So, Greatest Common Divisor of 905, 129, 387, 443 is 1
