Given numbers are 515,642,188
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 515,642,188 is 31079220.
Find LCM of 515,642,188 with Prime Factorization
| 2 | 515, 642, 188 |
| 515, 321, 94 |
Multiply the prime numbers at the bottom and the left side.
2 x 515 x 321 x 94 = 31079220
Therefore, the lowest common multiple of 515,642,188 is 31079220.
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.
515 x 642 x 188 = 62158440
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.
515 : 1, 5, 103, 515
642 : 1, 2, 3, 6, 107, 214, 321, 642
188 : 1, 2, 4, 47, 94, 188
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,642,188, is 1.
Now, the common factors can be found like this.
515:5x 103
642:2x 3x 107
188:2x 2x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 62158440/(1x2)
LCM = 62158440/2
LCM = 31079220
Thus, we can understand that the LCM of 515,642,188 is 31079220.
