GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(447, 846) = 126054
GCD(447, 846) = ( 447 x 846 ) / 126054
= 447 / 846
= 447
Step2:
LCM(3, 439) = 1317
GCD(3, 439) = ( 3 x 439 ) / 1317
= 3 / 439
= 3
Step3:
LCM(1, 390) = 390
GCD(1, 390) = ( 1 x 390 ) / 390
= 1 / 390
= 1
So, Greatest Common Divisor of 447, 846, 439, 390 is 1
