### How do you describe set?

A set in mathematics is a collection of well defined and distinct objects, considered as an object in its own right. The most basic properties are that a set “has” elements, and that two sets are equal (one and the same) if and only if every element of one is an element of the other.

What is the HCF of 43 91 and 183?

Bulusuchaitanya wrote: Find the greatest number that will divide 43, 91 and 183 so as to leave the same remainder in each case. Greatest number=HCF(91-43, 183-91, 183-43)=HCF(48, 92, 140)=4.

How do you find the HCF of 3 numbers?

To find out HCF of three given numbers using division method, Step 1: Find out HCF of any two numbers. Step 2: Find out the HCF of the third number and the HCF obtained in step 1. Step 3: HCF obtained in step 2 will be the HCF of the three numbers.

## What is the greatest number that divides 307 and 330?

Answer. Answer: The number will be HCF of 307 ” 3 = 304 and 330 ” 7 = 323.

### What is the greatest number which will divide 110 and 128 leaving a remainder 2 in each case?

Reminder 2. Therefore 110″2=108 AND 128″2=126 are fully divisible.

Hence the greatest number is 45.

What is the greatest number to divide 2400?

We have to find the greatest number that will divide 2400 and 1810 and leave remainders 6 and 4 respectively. So, the required number will divide (2400 ” 6) = 2394 and (1810 ” 4) = 1806 completely with zero remainder. Therefore, the required number is the greatest common factor of 2394 and 1806.
