Prove that 7×5×4×3+3×2 is composite no |
|
Answer» 7 X 6 x 5 x 4 x 3 x 2 x 1 + 5= 5040 + 5 = 5045= 5045 = 5 x 1009We know that a number is called a composite number if it has at least one FACTOR other than 1 and the number itself. Here, 5045 is the product of 2 prime factors 5 and 1009.Hence, 7 x 6 x 5 x 4 x 3 x 2 x 1 + 5 is a composite number. |
