Given numbers are 209,894,492,298
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 209,894,492,298 is 15321372.
Find LCM of 209,894,492,298 with Prime Factorization
| 2 | 209, 894, 492, 298 |
| 3 | 209, 447, 246, 149 |
| 149 | 209, 149, 82, 149 |
| 209, 1, 82, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 149 x 209 x 1 x 82 x 1 = 15321372
Therefore, the lowest common multiple of 209,894,492,298 is 15321372.
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.
209 x 894 x 492 x 298 = 27394613136
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.
209 : 1, 11, 19, 209
894 : 1, 2, 3, 6, 149, 298, 447, 894
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
298 : 1, 2, 149, 298
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,894,492,298, is 1.
Now, the common factors can be found like this.
209:11x 19
894:2x 3x 149
492:2x 2x 3x 41
298:2x 149
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 149 = 1788
Therefore, the value for common factors is 1788.
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 = 27394613136/(1x1788)
LCM = 27394613136/1788
LCM = 15321372
Thus, we can understand that the LCM of 209,894,492,298 is 15321372.
