Given numbers are 155,356,558,465
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 155,356,558,465 is 496620.
Find LCM of 155,356,558,465 with Prime Factorization
| 2 | 155, 356, 558, 465 |
| 3 | 155, 178, 279, 465 |
| 5 | 155, 178, 93, 155 |
| 31 | 31, 178, 93, 31 |
| 1, 178, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 31 x 1 x 178 x 3 x 1 = 496620
Therefore, the lowest common multiple of 155,356,558,465 is 496620.
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.
155 x 356 x 558 x 465 = 14317554600
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.
155 : 1, 5, 31, 155
356 : 1, 2, 4, 89, 178, 356
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
465 : 1, 3, 5, 15, 31, 93, 155, 465
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 155,356,558,465, is 1.
Now, the common factors can be found like this.
155:5x 31
356:2x 2x 89
558:2x 3x 3x 31
465:3x 5x 31
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 5x 31x 31 = 28830
Therefore, the value for common factors is 28830.
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 = 14317554600/(1x28830)
LCM = 14317554600/28830
LCM = 496620
Thus, we can understand that the LCM of 155,356,558,465 is 496620.
