2, 3 and 5
It is: 2*2*2*3*5*5 = 600
No because it has more than two factors
Find the prime factors first.
600 = 2 x 2 x 2 x 3 x 5 x 5
600=2^3*3*5^2 There are no two prime numbers that multiply to make 600. It takes 3 different prime numbers (2, 3, 5) to make 600, used as 6 factors (2*2*2*3*5*5).
It is: 743 because it only has two factors
The prime factors of 600 are 2, 2, 2, 3, 5, and 5. The prime factors of 1350 are 2, 3, 3, 3, 5, and 5. The prime factors they have in common are 2, 3, 5, and 5, so the greatest common factor is 2 x 3 x 5 x 5 = 150.
600 isn't a prime number.
It is: 2^3 times 3^1 times 5^2 = 600
2^3 x 3 x 5^2
The LCD is 600. Since the pair have no common prime factors, the LCD is the product of the two. 8 x 75 = 600
743 is a prime, having no factors other than 1 and itself. 465 and 600 obviously are composite, being multiples of 5, and 822 is an even number so it must be composite.
