Given numbers are 912,155,341,715
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 912,155,341,715 is 20214480.
Find LCM of 912,155,341,715 with Prime Factorization
| 5 | 912, 155, 341, 715 |
| 11 | 912, 31, 341, 143 |
| 31 | 912, 31, 31, 13 |
| 912, 1, 1, 13 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 31 x 912 x 1 x 1 x 13 = 20214480
Therefore, the lowest common multiple of 912,155,341,715 is 20214480.
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.
912 x 155 x 341 x 715 = 34465688400
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.
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
155 : 1, 5, 31, 155
341 : 1, 11, 31, 341
715 : 1, 5, 11, 13, 55, 65, 143, 715
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 912,155,341,715, is 1.
Now, the common factors can be found like this.
912:2x 2x 2x 2x 3x 19
155:5x 31
341:11x 31
715:5x 11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 11x 31 = 1705
Therefore, the value for common factors is 1705.
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 = 34465688400/(1x1705)
LCM = 34465688400/1705
LCM = 20214480
Thus, we can understand that the LCM of 912,155,341,715 is 20214480.
