120 = 2x2x2x3x5 = 23x31x51
factor --- 900 = 9x 100 = 3x3x5x5x2x2 120 = 4x30 = 2x2x2x3x5 pick the common factors GCF = 2x2x3x5 = 60
The answer is: 24 You do this for working out..... 120= 2x2x2x3x5 144= 2x2x2x2x3x3 2 2 2 3 are the same numbers so times them together.....24!
Prime factor each number. Use each prime the most it was used in any one number. 5=5 6=2x3 8=2x2x2 12=2x2x3 2x2x2x3x5=120
I factor each and then use each prime factor the most it was used in either number. 40=2x2x2x5 12=2x2x3 LCM=2x2x2x3x5=120 You can also write out the multiples of each until you have one that is in both lists. 12,24,36,48,60,72,84,96,108,120 40,80,120
Take the denominators and factor them into prime numbers. The LCM is the product of the prime numbers that were used the most. Here is an example. 1/30 and 1/24 30=2x3x5 24=2x2x2x3 LCM=2x2x2x3x5=120 Use that as the common denominator and multiply the numerator by the amount needed to multiply the denominator by to get the LCM.
1 * 120 2 * 60 3 * 40 4 * 30 5 * 24 6 * 20 8 * 15 10 * 12
The GCF of 120 and 200 is 40One of the simplest ways to work out the gcd of 2 numbers is to take their prime factors, and multiply together the ones each number has in common. In this case,120=2x2x2x3x5, 200=2x2x2x5x5they have three 2's and one 5 in common, highlighted in bold above, and 2x2x2x5=40.
To find the LCM of two numbers, you first need to break them down into their prime factors. In this case: 25 = 5x5 120 = 2x2x2x3x5 The next step is to identify any common factors. In this case, both have 5 as a prime factor, so cross off the duplicate. That leaves us with 2,2,2,3,5 and 5. Multiplying these together gives 600. Thus the LCM of 25 and 120 is 600.
Just multiply all these numbers together.(2 x 2) x 2 x 3 x 5 = 4 x 2 x 3 x 5(4 x 2) x 3 x 5 = 8 x 3 x 5(8 x 3) x 5 = 24 x 5 = 120
To find the greatest common factor of two numbers we first need to split them into their prime factors: 102 = 2x3x17 120 = 2x2x2x3x5 The next step is to identify the common factors. In this case both numbers have a 2 and a 3 as prime factors. To find the GCF we multiply these common factors together: 2x3 = 6 Thus 6 is the greatest common factor of 102 and 120.
To find the LCM of four numbers you first have to express these numbers as products of their prime factors. In the case of 3, 10, 12 and 8, this is: 3 = 3 10 = 2x5 12 = 2x2x3 8 = 2x2x2 The next step is to identify and discard any common prime factor duplicates. In this case, three numbers have a 2, so we can discard two of them. Two numbers have a second 2, so we can discard one of them. Two numbers have a 3, so we can discard one of them. Thus, the prime factors left are 2, 2, 2, 3 and 5. Multiply these together to find the LCM: 2x2x2x3x5 = 120 Thus the LCM of 3, 10, 12 and 8 is 120.
