Yes.

• 75 composite numbers are there till 100.
• 100-25=75.

Raffaello Sanzio da Urbino—known simply as Raphael to most—was part of the Holy Trinity of the High Renaissance, along with two other guys named Leonardo and Michelangelo. An artist of extraordinary refinement and deep feeling, Raphael was trained in the Umbrian style by the master painter Perugino and became renowned for his jewel-toned artworks distinguished by the almost evanescent delicacy of his figures’ features.

He was also a draftsman of the highest order, and this summer the Ashmolean Museum at Oxford is presenting 120 works on paper by the “prince of painters” in “Raphael: The Drawings” (through September 3), revealing the technical prowess and artistic genius that propelled him to fame in his own lifetime and far beyond.

To celebrate the artist’s enduring legacy, we surveyed 10 of Raphael’s most popular paintings (determined by their presence on Google Images, the number of reproductions created, and our own aesthetic enthusiasms)—and ranked them from one to 10, in order of their degree of accomplishment.

75890745 is not prime. 75890745 = 3 * 3 * 5 * 7 * 89 * 2707

The prime factors of 10,469 are: 19 and 29

19225 is a composite number. The positive integer factors of 19225 are:

1, 5, 25, 769, 3845, 19225

As an even number greater than 2, 1818 is divisible by 2 and therefore composite. Its positive integer factors are:

1, 2, 3, 6, 9, 18, 101, 202, 303, 606, 909, 1818

The answer is 20C10 which is 20!/[10!(20-10)!] = 184756

Any number that ends with 0, 2, 4, 6 or 8 is a multiple of 2.

Green and prime numbers should be red.

A composite number, because there are factors other than itself and one: 2, 3, 4, 6, 8, 12.

No, prime numbers have only two factors: 1 and itself. Composite numbers have at least 3 factors.

5563 is a prime number. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.

34 is a composite number because it has 4 factors: 1, 2, 17, and 34.

363 = 3 times 121 and is therefore composite and not prime.

248 is a composite number because it has factors other than 1 and itself. It is not a prime number.

For example, 248 is an even number, which means it is also divisible by 2.

457 is prime. It is only evenly divisible by itself and one.

47 is prime

68 = 2 x 34

266 = 2 x 133

The prime factors of 78 are 2, 3, and 13.
