- 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.
Question 1:
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:
A. 75
B. 81
C. 85
Feedback ince 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 = (551/29 ) = 19 ;
Third number = (1073 / 29) = 37
Therefore, Required sum = (19 + 29 + 37) = 85.
