Question

Explain why 3 multiply by 5 multiply by 7 multiply by 7 is a composite number. please fast answer me only in 2 minutes.​

Answer 1

A composite number is a number that is divisible by another number other than by itself and one. The number 2 is the only even prime number. All other even numbers are composite numbers.

As per BODMAS rule:

3 x 5 x 7 + 7 = 105 + 7 = 112.

112 is an even number and is therefore a composite number.

Also, 112 is divisible by other numbers such as 2, 4, 7, 8, 14, 16, 28 and 56 apart from itself (112) and 1

Answer 2

Answer:

this is so because when we multiply 3×5×7×7 then we get answer as 735 and it composite no. as it can divided by many numbers like 3and 5

HERE IS THE DEFINATION OF COMPOSITE NUMBER WITH AN EXAMPLE FOR YOUR BETTER UNDERSTANDING

A composite number is a positive integer that can be formed by multiplying two smaller positive integers. Equivalently, it is a positive integer that has at least one divisor other than 1 and itself. ... Likewise, the integers 2 and 3 are not composite numbers because each of them can only be divided by one and itself.
