The LCM of 968,133,840,155 is 59865960.
Find LCM of 968,133,840,155 with Prime Factorization
| 2 | 968, 133, 840, 155 |
| 2 | 484, 133, 420, 155 |
| 2 | 242, 133, 210, 155 |
| 5 | 121, 133, 105, 155 |
| 7 | 121, 133, 21, 31 |
| 121, 19, 3, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 7 x 121 x 19 x 3 x 31 = 59865960
Therefore, the lowest common multiple of 968,133,840,155 is 59865960.
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.
968 x 133 x 840 x 155 = 16762468800
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.
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
133 : 1, 7, 19, 133
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
155 : 1, 5, 31, 155
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 968,133,840,155, is 1.
Now, the common factors can be found like this.
968:2x 2x 2x 11x 11
133:7x 19
840:2x 2x 2x 3x 5x 7
155:5x 31
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 5x 7 = 280
Therefore, the value for common factors is 280.
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 = 16762468800/(1x280)
LCM = 16762468800/280
LCM = 59865960
Thus, we can understand that the LCM of 968,133,840,155 is 59865960.
