Discussion :: Problems on H.C.F and L.C.M
-
Three numbers which are co-prime to each other are such that the product of the first two is 551 and that of the last two is 1073. The sum of the three numbers is:
Answer : Option C
Explanation :
Since the numbers are co-prime, they contain only 1 as the common factor.
Also, the given two products have the middle number in common.
So, middle number = H.C.F. of 551 and 1073 = 29;
First number =\( [\frac {551 } { 29 }] =19\) Third number =\( [\frac { 1027 } { 2 9} ]=37\)
Required sum = (19 + 29 + 37) = 85.
