Question

explain why 7×11×13×1×2×3+11 is a composite number....​

Answer 1

Step-by-step explanation:

using the divisibility rule of 2 which states that for a number to be divisible by 2 , the unit digit must have 0,2,4,6 or 8 in units place . here , 1012 has 2 in ones place , so it is divisible by 2. ... the number is also divisible by 11. so, it can be said that 7×11×13+11 which is 1012 is a composite number.

Answer 2

composite numher is a number which has only 1 factor ..

so here u can take 11 as a factor

then

11 (7×1×13×1×2×3+1)

we can easily see here 11 has more then 1 factor so it is composite number
