Given numbers are 310,912,730,992
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 310,912,730,992 is 20638560.
Find LCM of 310,912,730,992 with Prime Factorization
| 2 | 310, 912, 730, 992 |
| 2 | 155, 456, 365, 496 |
| 2 | 155, 228, 365, 248 |
| 2 | 155, 114, 365, 124 |
| 5 | 155, 57, 365, 62 |
| 31 | 31, 57, 73, 62 |
| 1, 57, 73, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 31 x 1 x 57 x 73 x 2 = 20638560
Therefore, the lowest common multiple of 310,912,730,992 is 20638560.
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.
310 x 912 x 730 x 992 = 204734515200
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.
310 : 1, 2, 5, 10, 31, 62, 155, 310
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
730 : 1, 2, 5, 10, 73, 146, 365, 730
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 310,912,730,992, is 2.
Now, the common factors can be found like this.
310:2x 5x 31
912:2x 2x 2x 2x 3x 19
730:2x 5x 73
992:2x 2x 2x 2x 2x 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 2x 2x 5x 31 = 4960
Therefore, the value for common factors is 4960.
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 = 204734515200/(2x4960)
LCM = 204734515200/9920
LCM = 20638560
Thus, we can understand that the LCM of 310,912,730,992 is 20638560.
