To find the highest common factor (HCF) of 735 and 945, we first need to factorize both numbers. The prime factors of 735 are 3 x 5 x 7 x 7, and the prime factors of 945 are 3 x 3 x 3 x 5 x 7. To find the HCF, we identify the common prime factors and multiply them together: 3 x 5 x 7 = 105. Therefore, the highest common factor of 735 and 945 is 105.
As a product of its prime factors: 3*5*7*7 = 735
735 = 3 × 5 × 7 × 7
3 x 3 x 3 x 5 x 7 = 945
Answer:735 is not a prime number. It is a composite number.Definition:A prime number has exactly two factors: 1 (also known as unity) and itself. A composite number has more than two factors; in other words, it has at least one factor besides 1 and itself.Explanation:Any number ending in 0 or 5 is evenly divisible by 5, so it also has 5 as a factor. Thus, 735 is divisible by 5, so it is a composite number.
