Given numbers are 153,428,309,988
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 153,428,309,988 is 1665978444.
Find LCM of 153,428,309,988 with Prime Factorization
| 2 | 153, 428, 309, 988 |
| 2 | 153, 214, 309, 494 |
| 3 | 153, 107, 309, 247 |
| 51, 107, 103, 247 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 51 x 107 x 103 x 247 = 1665978444
Therefore, the lowest common multiple of 153,428,309,988 is 1665978444.
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 428 x 309 x 988 = 19991741328
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
428 : 1, 2, 4, 107, 214, 428
309 : 1, 3, 103, 309
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 153,428,309,988, is 1.
Now, the common factors can be found like this.
153:3x 3x 17
428:2x 2x 107
309:3x 103
988:2x 2x 13x 19
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 3 = 12
Therefore, the value for common factors is 12.
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 = 19991741328/(1x12)
LCM = 19991741328/12
LCM = 1665978444
Thus, we can understand that the LCM of 153,428,309,988 is 1665978444.
