Given numbers are 189,278,549,384,890
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 189,278,549,384,890 is 91280165760.
Find LCM of 189,278,549,384,890 with Prime Factorization
| 2 | 189, 278, 549, 384, 890 |
| 3 | 189, 139, 549, 192, 445 |
| 3 | 63, 139, 183, 64, 445 |
| 21, 139, 61, 64, 445 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 21 x 139 x 61 x 64 x 445 = 91280165760
Therefore, the lowest common multiple of 189,278,549,384,890 is 91280165760.
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.
189 x 278 x 549 x 384 x 890 = 9858257902080
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.
189 : 1, 3, 7, 9, 21, 27, 63, 189
278 : 1, 2, 139, 278
549 : 1, 3, 9, 61, 183, 549
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
890 : 1, 2, 5, 10, 89, 178, 445, 890
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,278,549,384,890, is 1.
Now, the common factors can be found like this.
189:3x 3x 3x 7
278:2x 139
549:3x 3x 61
384:2x 2x 2x 2x 2x 2x 2x 3
890:2x 5x 89
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 3x 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 9858257902080/(1x108)
LCM = 9858257902080/108
LCM = 91280165760
Thus, we can understand that the LCM of 189,278,549,384,890 is 91280165760.
