Given numbers are 143,495,647,760
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 143,495,647,760 is 632843640.
Find LCM of 143,495,647,760 with Prime Factorization
| 5 | 143, 495, 647, 760 |
| 11 | 143, 99, 647, 152 |
| 13, 9, 647, 152 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 13 x 9 x 647 x 152 = 632843640
Therefore, the lowest common multiple of 143,495,647,760 is 632843640.
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.
143 x 495 x 647 x 760 = 34806400200
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.
143 : 1, 11, 13, 143
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
647 : 1, 647
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 143,495,647,760, is 1.
Now, the common factors can be found like this.
143:11x 13
495:3x 3x 5x 11
647:647
760:2x 2x 2x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 11 = 55
Therefore, the value for common factors is 55.
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 = 34806400200/(1x55)
LCM = 34806400200/55
LCM = 632843640
Thus, we can understand that the LCM of 143,495,647,760 is 632843640.
