How do you find the prime factor of 84?
Use a factor tree. 84 42,2 21,2,2 7,3,2,2
How do you find the average for the following group of numbers 85 92 84 85 96 95?
add them all up and divide by how many numbers there are so..... 85+92+84+85+96+95=? and divide by 6

How do you find the least common denominator of 5 over 7 and 5 over 6 and and 3 over 4?
The LCD is the Least Common Multiple of all denominator. To find the LCM, factor all three numbers 7 is prime 6 is [3 2] 4 is [2 2] Multiply all three numbers to get 168, but since 6 and 4 have a 2 in common, divide the total by 2 to get 84. Your new fractions are (60 / 84) (70 / 84) and (63 / 84) A quick way to find 84 is to take the two highest numbers and multiply them together. Check to see if the lowest number can divide it. If it cannot, add another multiple of what you got. For example here, 7*6 is 42, but 4 does not divide it, so add another 42 to get 84. now 4 divides it, so that is the answer.
What prime numbers equal 84?
No prime numbers equal 84. The only number equal to 84 is 84,and it isn't a prime number.The prime factors of 84 are: 1, 2, 2, 3, and 7
What numbers can divide 84 evenly?
2, 3, 4, 6, 7, 12, 14, 21, 28, 42. Also 1 and 84, but Mathematicians don't usually regard these as proper divisors.
How do you break apart 84 into simple numbers to divide?
84 is already a simple number to divide. Do you mean "factorize"? : first try dividing by 2. If that works try another 2 until it doesn't divide. Then try 3 and follow the same rule. 4 is pointless since the divides by 2 would have dealt with that. Then try 5. 6 is covered by 2 and 3, then 7 etc etc.
What are 4 prime numbers mutiplied to get 84?
84 = 2 * 2 * 3 * 7
What is the least common multiple of 12 and 28?
The LCM of 12 and 28 is 84. For small numbers, the easy way is to find the GCF and divide one of them by it, then multiply the result by the other number. Factors of 12 are [2 2 3] Factors of 28 are [2 2 7] GCF=[2] = 4 Divide 28 by 4=7 and 7*12=84. The proper way (which works for all numbers) is to take the highest power of all factors. 12 is 2^2 * 3^1 28 is 2^2 * 7^1 LCM is 2^2 * 3^1 * 7^1 (since 2^2 is the highest power of 2 in both numbers) 4 * 3 * 7 = 84
What is the LCM of 84 and 2?
The LCM of the given two numbers is 84
