Given numbers are 152,644,581,816
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 152,644,581,816 is 207179952.
Find LCM of 152,644,581,816 with Prime Factorization
| 2 | 152, 644, 581, 816 |
| 2 | 76, 322, 581, 408 |
| 2 | 38, 161, 581, 204 |
| 7 | 19, 161, 581, 102 |
| 19, 23, 83, 102 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 19 x 23 x 83 x 102 = 207179952
Therefore, the lowest common multiple of 152,644,581,816 is 207179952.
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.
152 x 644 x 581 x 816 = 46408309248
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.
152 : 1, 2, 4, 8, 19, 38, 76, 152
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
581 : 1, 7, 83, 581
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 152,644,581,816, is 1.
Now, the common factors can be found like this.
152:2x 2x 2x 19
644:2x 2x 7x 23
581:7x 83
816:2x 2x 2x 2x 3x 17
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 7 = 224
Therefore, the value for common factors is 224.
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 = 46408309248/(1x224)
LCM = 46408309248/224
LCM = 207179952
Thus, we can understand that the LCM of 152,644,581,816 is 207179952.
