Given numbers are 879,638,638,222
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 879,638,638,222 is 20749674.
Find LCM of 879,638,638,222 with Prime Factorization
| 2 | 879, 638, 638, 222 |
| 3 | 879, 319, 319, 111 |
| 11 | 293, 319, 319, 37 |
| 29 | 293, 29, 29, 37 |
| 293, 1, 1, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 29 x 293 x 1 x 1 x 37 = 20749674
Therefore, the lowest common multiple of 879,638,638,222 is 20749674.
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.
879 x 638 x 638 x 222 = 79429752072
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.
879 : 1, 3, 293, 879
638 : 1, 2, 11, 22, 29, 58, 319, 638
638 : 1, 2, 11, 22, 29, 58, 319, 638
222 : 1, 2, 3, 6, 37, 74, 111, 222
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 879,638,638,222, is 1.
Now, the common factors can be found like this.
879:3x 293
638:2x 11x 29
638:2x 11x 29
222:2x 3x 37
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 11x 29 = 3828
Therefore, the value for common factors is 3828.
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 = 79429752072/(1x3828)
LCM = 79429752072/3828
LCM = 20749674
Thus, we can understand that the LCM of 879,638,638,222 is 20749674.
