Given numbers are 131,428,238,107
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 131,428,238,107 is 6672092.
Find LCM of 131,428,238,107 with Prime Factorization
| 2 | 131, 428, 238, 107 |
| 107 | 131, 214, 119, 107 |
| 131, 2, 119, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 107 x 131 x 2 x 119 x 1 = 6672092
Therefore, the lowest common multiple of 131,428,238,107 is 6672092.
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.
131 x 428 x 238 x 107 = 1427827688
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.
131 : 1, 131
428 : 1, 2, 4, 107, 214, 428
238 : 1, 2, 7, 14, 17, 34, 119, 238
107 : 1, 107
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 131,428,238,107, is 1.
Now, the common factors can be found like this.
131:131
428:2x 2x 107
238:2x 7x 17
107:107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 107 = 214
Therefore, the value for common factors is 214.
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 = 1427827688/(1x214)
LCM = 1427827688/214
LCM = 6672092
Thus, we can understand that the LCM of 131,428,238,107 is 6672092.
