Given numbers are 178,642,353,308
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 178,642,353,308 is 3106135956.
Find LCM of 178,642,353,308 with Prime Factorization
| 2 | 178, 642, 353, 308 |
| 89, 321, 353, 154 |
Multiply the prime numbers at the bottom and the left side.
2 x 89 x 321 x 353 x 154 = 3106135956
Therefore, the lowest common multiple of 178,642,353,308 is 3106135956.
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.
178 x 642 x 353 x 308 = 12424543824
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.
178 : 1, 2, 89, 178
642 : 1, 2, 3, 6, 107, 214, 321, 642
353 : 1, 353
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 178,642,353,308, is 1.
Now, the common factors can be found like this.
178:2x 89
642:2x 3x 107
353:353
308:2x 2x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 12424543824/(1x4)
LCM = 12424543824/4
LCM = 3106135956
Thus, we can understand that the LCM of 178,642,353,308 is 3106135956.
