Given numbers are 549,826,770,422
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 549,826,770,422 is 5262565770.
Find LCM of 549,826,770,422 with Prime Factorization
| 2 | 549, 826, 770, 422 |
| 7 | 549, 413, 385, 211 |
| 549, 59, 55, 211 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 549 x 59 x 55 x 211 = 5262565770
Therefore, the lowest common multiple of 549,826,770,422 is 5262565770.
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.
549 x 826 x 770 x 422 = 147351841560
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.
549 : 1, 3, 9, 61, 183, 549
826 : 1, 2, 7, 14, 59, 118, 413, 826
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
422 : 1, 2, 211, 422
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 549,826,770,422, is 1.
Now, the common factors can be found like this.
549:3x 3x 61
826:2x 7x 59
770:2x 5x 7x 11
422:2x 211
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 7 = 28
Therefore, the value for common factors is 28.
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 = 147351841560/(1x28)
LCM = 147351841560/28
LCM = 5262565770
Thus, we can understand that the LCM of 549,826,770,422 is 5262565770.
