Given numbers are 415, 387, 954, 818
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(415, 387) = 160605
GCD(415, 387) = ( 415 x 387 ) / 160605
= 415 / 387
= 415
Step2:
LCM(1, 954) = 954
GCD(1, 954) = ( 1 x 954 ) / 954
= 1 / 954
= 1
Step3:
LCM(1, 818) = 818
GCD(1, 818) = ( 1 x 818 ) / 818
= 1 / 818
= 1
So, Greatest Common Divisor of 415, 387, 954, 818 is 1
