The product of two numbers is 1320 and their HCF is 6. The LCM of the numbers is
(A) 220
(B) 1314
(C) 1326
(D) 7920
Ans: A
LCM = $$({Product of number} / {HCF} )$$= $${1320} / {6}$$ = 220.
Question: 2
The greatest four digit number which is exactly divisible by each one of the numbers 12, 18, 21 and 28
(A) 9288
(B) 9828
(C) 9882
(D) 9928
Ans: B
The greatest 4 digit number is 9999
The LCM of 12, 18, 21, 28 is 252
On dividing 9999 by 252 the remainder comes out to be 171
∴ Required number = 9999 – 171 = 9828.
Question: 3
When Seeta made necklaces of either 16 beads, 20 beads or 36 beads, not a single bead was left over. What could be the least number of beads Seeta had?
(A) 700
(B) 710
(C) 720
(D) 740
Ans: C
Required number of beads = L.C.M. of 16, 20, 36 = 720.
Question: 4
The least number should be added to 2497 so that the sum is exactly divisible by 5, 6, 4 and 3 is
(A) 3
(B) 13
(C) 23
(D) 33
Ans: C
L.C.M. of 5, 6, 4 and 3 = 60.
On dividing 2497 by 60, the remainder is 37.
∴ Number to be added = (60 – 37) = 23.
Question: 5
Three sets of English, Mathematics and Science books containing 336, 240 and 96 books respectively have to be stacked in such a way that all the books are stored subject wise and the height of each stack is the same. Total number of stacks will be
(A) 7
(B) 14
(C) 21
(D) 28
Ans: B
Number of books in each stack = H.C.F. of 336, 240 and 96 = 48.
Hence total number of stacks = $$({336 + 240 + 96} / 48)$$ = $${672} / {48}$$ = 14.
