To determine if 4900 is a prime number or a composite number, we simply look at the factors for 4900.
If the factors of 4900 are only 4900 and 1, then we know that 4900 is a prime number. Otherwise, 4900 is a composite number.
To explain better, if 4900 is only divisible by 1 and 4900, then it is a prime number, and if 4900 is divisible by more than 4900 and 1, then it is a composite number.
The factors of 4900 are as follows:
1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 49, 50, 70, 98, 100, 140, 175, 196, 245, 350, 490, 700, 980, 1225, 2450, 4900
Therefore, since 4900 is divisible by more than one and itself, the answer to the
question "Is 4900 prime or composite?" is highlighted in blue below.
