Given numbers are 401,758,442,390,302
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 401,758,442,390,302 is 152150736270.
Find LCM of 401,758,442,390,302 with Prime Factorization
| 2 | 401, 758, 442, 390, 302 |
| 13 | 401, 379, 221, 195, 151 |
| 401, 379, 17, 15, 151 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 401 x 379 x 17 x 15 x 151 = 152150736270
Therefore, the lowest common multiple of 401,758,442,390,302 is 152150736270.
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.
401 x 758 x 442 x 390 x 302 = 15823676572080
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.
401 : 1, 401
758 : 1, 2, 379, 758
442 : 1, 2, 13, 17, 26, 34, 221, 442
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
302 : 1, 2, 151, 302
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,758,442,390,302, is 1.
Now, the common factors can be found like this.
401:401
758:2x 379
442:2x 13x 17
390:2x 3x 5x 13
302:2x 151
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 2x 13 = 104
Therefore, the value for common factors is 104.
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 = 15823676572080/(1x104)
LCM = 15823676572080/104
LCM = 152150736270
Thus, we can understand that the LCM of 401,758,442,390,302 is 152150736270.
