Given numbers are 170,638,495,803,768
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 170,638,495,803,768 is 4560526080.
Find LCM of 170,638,495,803,768 with Prime Factorization
| 2 | 170, 638, 495, 803, 768 |
| 3 | 85, 319, 495, 803, 384 |
| 5 | 85, 319, 165, 803, 128 |
| 11 | 17, 319, 33, 803, 128 |
| 17, 29, 3, 73, 128 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 17 x 29 x 3 x 73 x 128 = 4560526080
Therefore, the lowest common multiple of 170,638,495,803,768 is 4560526080.
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.
170 x 638 x 495 x 803 x 768 = 33109419340800
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.
170 : 1, 2, 5, 10, 17, 34, 85, 170
638 : 1, 2, 11, 22, 29, 58, 319, 638
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
803 : 1, 11, 73, 803
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 170,638,495,803,768, is 1.
Now, the common factors can be found like this.
170:2x 5x 17
638:2x 11x 29
495:3x 3x 5x 11
803:11x 73
768:2x 2x 2x 2x 2x 2x 2x 2x 3
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 3x 5x 11x 11 = 7260
Therefore, the value for common factors is 7260.
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 = 33109419340800/(1x7260)
LCM = 33109419340800/7260
LCM = 4560526080
Thus, we can understand that the LCM of 170,638,495,803,768 is 4560526080.
