Given numbers are 290,667,130,142
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 290,667,130,142 is 6156410.
Find LCM of 290,667,130,142 with Prime Factorization
| 2 | 290, 667, 130, 142 |
| 5 | 145, 667, 65, 71 |
| 29 | 29, 667, 13, 71 |
| 1, 23, 13, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 29 x 1 x 23 x 13 x 71 = 6156410
Therefore, the lowest common multiple of 290,667,130,142 is 6156410.
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.
290 x 667 x 130 x 142 = 3570717800
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.
290 : 1, 2, 5, 10, 29, 58, 145, 290
667 : 1, 23, 29, 667
130 : 1, 2, 5, 10, 13, 26, 65, 130
142 : 1, 2, 71, 142
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 290,667,130,142, is 1.
Now, the common factors can be found like this.
290:2x 5x 29
667:23x 29
130:2x 5x 13
142:2x 71
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 5x 29 = 580
Therefore, the value for common factors is 580.
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 = 3570717800/(1x580)
LCM = 3570717800/580
LCM = 6156410
Thus, we can understand that the LCM of 290,667,130,142 is 6156410.
