Given numbers are 408,155,210,959
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 408,155,210,959 is 60647160.
Find LCM of 408,155,210,959 with Prime Factorization
| 2 | 408, 155, 210, 959 |
| 3 | 204, 155, 105, 959 |
| 5 | 68, 155, 35, 959 |
| 7 | 68, 31, 7, 959 |
| 68, 31, 1, 137 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 68 x 31 x 1 x 137 = 60647160
Therefore, the lowest common multiple of 408,155,210,959 is 60647160.
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.
408 x 155 x 210 x 959 = 12735903600
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.
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
155 : 1, 5, 31, 155
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
959 : 1, 7, 137, 959
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 408,155,210,959, is 1.
Now, the common factors can be found like this.
408:2x 2x 2x 3x 17
155:5x 31
210:2x 3x 5x 7
959:7x 137
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 7 = 210
Therefore, the value for common factors is 210.
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 = 12735903600/(1x210)
LCM = 12735903600/210
LCM = 60647160
Thus, we can understand that the LCM of 408,155,210,959 is 60647160.
