Given numbers are 153,454,663,772
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 153,454,663,772 is 348560316.
Find LCM of 153,454,663,772 with Prime Factorization
| 2 | 153, 454, 663, 772 |
| 3 | 153, 227, 663, 386 |
| 17 | 51, 227, 221, 386 |
| 3, 227, 13, 386 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 3 x 227 x 13 x 386 = 348560316
Therefore, the lowest common multiple of 153,454,663,772 is 348560316.
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.
153 x 454 x 663 x 772 = 35553152232
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.
153 : 1, 3, 9, 17, 51, 153
454 : 1, 2, 227, 454
663 : 1, 3, 13, 17, 39, 51, 221, 663
772 : 1, 2, 4, 193, 386, 772
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 153,454,663,772, is 1.
Now, the common factors can be found like this.
153:3x 3x 17
454:2x 227
663:3x 13x 17
772:2x 2x 193
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 17 = 102
Therefore, the value for common factors is 102.
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 = 35553152232/(1x102)
LCM = 35553152232/102
LCM = 348560316
Thus, we can understand that the LCM of 153,454,663,772 is 348560316.
