Given numbers are 278,391,146,901
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 278,391,146,901 is 420552562.
Find LCM of 278,391,146,901 with Prime Factorization
| 2 | 278, 391, 146, 901 |
| 17 | 139, 391, 73, 901 |
| 139, 23, 73, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 139 x 23 x 73 x 53 = 420552562
Therefore, the lowest common multiple of 278,391,146,901 is 420552562.
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.
278 x 391 x 146 x 901 = 14298787108
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.
278 : 1, 2, 139, 278
391 : 1, 17, 23, 391
146 : 1, 2, 73, 146
901 : 1, 17, 53, 901
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,391,146,901, is 1.
Now, the common factors can be found like this.
278:2x 139
391:17x 23
146:2x 73
901:17x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17 = 34
Therefore, the value for common factors is 34.
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 = 14298787108/(1x34)
LCM = 14298787108/34
LCM = 420552562
Thus, we can understand that the LCM of 278,391,146,901 is 420552562.
