GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(258, 891) = 76626
GCD(258, 891) = ( 258 x 891 ) / 76626
= 258 / 891
= 258
Step2:
LCM(3, 439) = 1317
GCD(3, 439) = ( 3 x 439 ) / 1317
= 3 / 439
= 3
Step3:
LCM(1, 408) = 408
GCD(1, 408) = ( 1 x 408 ) / 408
= 1 / 408
= 1
So, Greatest Common Divisor of 258, 891, 439, 408 is 1
