Find LCM of 120,600,742,968,542 with Prime Factorization
| 2 | 120, 600, 742, 968, 542 |
| 2 | 60, 300, 371, 484, 271 |
| 2 | 30, 150, 371, 242, 271 |
| 3 | 15, 75, 371, 121, 271 |
| 5 | 5, 25, 371, 121, 271 |
| 1, 5, 371, 121, 271 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 1 x 5 x 371 x 121 x 271 = 7299276600
Therefore, the lowest common multiple of 120,600,742,968,542 is 7299276600.
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.
120 x 600 x 742 x 968 x 542 = 28029222144000
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.
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
600 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 25, 30, 40, 50, 60, 75, 100, 120, 150, 200, 300, 600
742 : 1, 2, 7, 14, 53, 106, 371, 742
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
542 : 1, 2, 271, 542
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 120,600,742,968,542, is 2.
Now, the common factors can be found like this.
120:2x 2x 2x 3x 5
600:2x 2x 2x 3x 5x 5
742:2x 7x 53
968:2x 2x 2x 11x 11
542:2x 271
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 2x 2x 2x 3x 5 = 1920
Therefore, the value for common factors is 1920.
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 = 28029222144000/(2x1920)
LCM = 28029222144000/3840
LCM = 7299276600
Thus, we can understand that the LCM of 120,600,742,968,542 is 7299276600.
