Given numbers are 118,644,236,180
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 118,644,236,180 is 1709820.
Find LCM of 118,644,236,180 with Prime Factorization
| 2 | 118, 644, 236, 180 |
| 2 | 59, 322, 118, 90 |
| 59 | 59, 161, 59, 45 |
| 1, 161, 1, 45 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 59 x 1 x 161 x 1 x 45 = 1709820
Therefore, the lowest common multiple of 118,644,236,180 is 1709820.
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.
118 x 644 x 236 x 180 = 3228140160
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.
118 : 1, 2, 59, 118
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
236 : 1, 2, 4, 59, 118, 236
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 118,644,236,180, is 2.
Now, the common factors can be found like this.
118:2x 59
644:2x 2x 7x 23
236:2x 2x 59
180:2x 2x 3x 3x 5
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 59 = 944
Therefore, the value for common factors is 944.
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 = 3228140160/(2x944)
LCM = 3228140160/1888
LCM = 1709820
Thus, we can understand that the LCM of 118,644,236,180 is 1709820.
