Given numbers are 213,869,537,639
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 213,869,537,639 is 99397089.
Find LCM of 213,869,537,639 with Prime Factorization
| 3 | 213, 869, 537, 639 |
| 71 | 71, 869, 179, 213 |
| 1, 869, 179, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 71 x 1 x 869 x 179 x 3 = 99397089
Therefore, the lowest common multiple of 213,869,537,639 is 99397089.
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.
213 x 869 x 537 x 639 = 63514739871
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.
213 : 1, 3, 71, 213
869 : 1, 11, 79, 869
537 : 1, 3, 179, 537
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 213,869,537,639, is 1.
Now, the common factors can be found like this.
213:3x 71
869:11x 79
537:3x 179
639:3x 3x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 71 = 639
Therefore, the value for common factors is 639.
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 = 63514739871/(1x639)
LCM = 63514739871/639
LCM = 99397089
Thus, we can understand that the LCM of 213,869,537,639 is 99397089.
