Question
The total and the difference of L.C.M and H.C.F of two
numbers are 432 and 96. If one of the numbers is 24, what is the other number?Solution
ATQ,
Let the L.C.M and the H.C.F of the two numbers be 'a' and 'b' respectively
Then, (a + b) = 432
And (a - b) = 96
So, (a + b) + (a - b) = 432 + 96 = 528
Or, a = 528 ÷ 2 = 264
So, b = 432 - 264 = 168
The product of two numbers is equal to the product of their L.C.M and H.C.FSo, required number = (264 × 168) ÷ 24 = 1848

Find the greatest number that will divide 115, 149 and 183 leaving remainders 3, 5, 7 respectively.
The ratio of two numbers is 6:14 and their LCM is 126. The numbers are:
The least number which when divided by 4, 6, 10 and 12 leave zero remainder in each case and when divided by 13 leaves a remainder of 8 is:
If the sum of 2 numbers is 185, their LCM is 1700 and HCF is 5. Then the difference between 2 numbers is:
The sum and difference of the Least Common Multiple (L.C.M) and Highest Common Factor (H.C.F) of two numbers are 216 and 184, respectively. One of the ...
