Given numbers are 331,543,392,152,390
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 331,543,392,152,390 is 87012339960.
Find LCM of 331,543,392,152,390 with Prime Factorization
| 2 | 331, 543, 392, 152, 390 |
| 2 | 331, 543, 196, 76, 195 |
| 2 | 331, 543, 98, 38, 195 |
| 3 | 331, 543, 49, 19, 195 |
| 331, 181, 49, 19, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 331 x 181 x 49 x 19 x 65 = 87012339960
Therefore, the lowest common multiple of 331,543,392,152,390 is 87012339960.
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.
331 x 543 x 392 x 152 x 390 = 4176592318080
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.
331 : 1, 331
543 : 1, 3, 181, 543
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
152 : 1, 2, 4, 8, 19, 38, 76, 152
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 331,543,392,152,390, is 1.
Now, the common factors can be found like this.
331:331
543:3x 181
392:2x 2x 2x 7x 7
152:2x 2x 2x 19
390:2x 3x 5x 13
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 2x 3 = 48
Therefore, the value for common factors is 48.
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 = 4176592318080/(1x48)
LCM = 4176592318080/48
LCM = 87012339960
Thus, we can understand that the LCM of 331,543,392,152,390 is 87012339960.
