Given numbers are 387, 817, 905, 909
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(387, 817) = 7353
GCD(387, 817) = ( 387 x 817 ) / 7353
= 387 / 817
= 387
Step2:
LCM(43, 905) = 38915
GCD(43, 905) = ( 43 x 905 ) / 38915
= 43 / 905
= 43
Step3:
LCM(1, 909) = 909
GCD(1, 909) = ( 1 x 909 ) / 909
= 1 / 909
= 1
So, Greatest Common Divisor of 387, 817, 905, 909 is 1
