Given numbers are 636,422,964,894
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 636,422,964,894 is 4818844164.
Find LCM of 636,422,964,894 with Prime Factorization
| 2 | 636, 422, 964, 894 |
| 2 | 318, 211, 482, 447 |
| 3 | 159, 211, 241, 447 |
| 53, 211, 241, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 53 x 211 x 241 x 149 = 4818844164
Therefore, the lowest common multiple of 636,422,964,894 is 4818844164.
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.
636 x 422 x 964 x 894 = 231304519872
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.
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
422 : 1, 2, 211, 422
964 : 1, 2, 4, 241, 482, 964
894 : 1, 2, 3, 6, 149, 298, 447, 894
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 636,422,964,894, is 2.
Now, the common factors can be found like this.
636:2x 2x 3x 53
422:2x 211
964:2x 2x 241
894:2x 3x 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 2x 3 = 24
Therefore, the value for common factors is 24.
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 = 231304519872/(2x24)
LCM = 231304519872/48
LCM = 4818844164
Thus, we can understand that the LCM of 636,422,964,894 is 4818844164.
