Find LCM of 723,320,955,321,240 with Prime Factorization
| 2 | 723, 320, 955, 321, 240 |
| 2 | 723, 160, 955, 321, 120 |
| 2 | 723, 80, 955, 321, 60 |
| 2 | 723, 40, 955, 321, 30 |
| 3 | 723, 20, 955, 321, 15 |
| 5 | 241, 20, 955, 107, 5 |
| 241, 4, 191, 107, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 5 x 241 x 4 x 191 x 107 x 1 = 4728304320
Therefore, the lowest common multiple of 723,320,955,321,240 is 4728304320.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
723 x 320 x 955 x 321 x 240 = 17021895552000
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
723 : 1, 3, 241, 723
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
955 : 1, 5, 191, 955
321 : 1, 3, 107, 321
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 723,320,955,321,240, is 1.
Now, the common factors can be found like this.
723:3x 241
320:2x 2x 2x 2x 2x 2x 5
955:5x 191
321:3x 107
240:2x 2x 2x 2x 3x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 3x 3x 5x 5 = 3600
Therefore, the value for common factors is 3600.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 17021895552000/(1x3600)
LCM = 17021895552000/3600
LCM = 4728304320
Thus, we can understand that the LCM of 723,320,955,321,240 is 4728304320.
