2 to the second power is 4, which isn't a factor of 54. 3 to the second power is 9, which is a factor of 54 but isn't prime. 4 divided by 9 is 4/9, which isn't prime and isn't a factor of 54.
The only prime factor of 49 is seven (7).
The greatest factor of any number is the number itself. The second greatest factor of any even number is half the number. The second greatest factor of any composite number is the number divided by its smallest prime factor. The second greatest factor of any prime number is 1.
4 to the second power times four
1.5
That's a prime factor.
prime factor = prime number which can be divided into the given number with no remainder ie 2
no because 21 can be divided by 3, 7, and itself now 22 is not a prime factor either because it can be divided by 2 and 11 and of course itself, And prime factor is a number that can only divided by 1 and itself
Its prime factor is 2 and as a product of its prime factor 2 to the power of 7 = 128
a number that can be divided by itself or by one
It can only be divided by itself and one.
This is a LCM question, so factor all and find the highest power of each prime factor. 2 is prime 3 is prime 5 is prime 6 is [2 3] 7 is prime. LCM is [2] [3] [5] [7] so the answer is 210◄
2 x 3 x 3 = 18
