Given numbers are 926,221,788,998,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 926,221,788,998,642 is 12915316703796.
Find LCM of 926,221,788,998,642 with Prime Factorization
| 2 | 926, 221, 788, 998, 642 |
| 463, 221, 394, 499, 321 |
Multiply the prime numbers at the bottom and the left side.
2 x 463 x 221 x 394 x 499 x 321 = 12915316703796
Therefore, the lowest common multiple of 926,221,788,998,642 is 12915316703796.
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.
926 x 221 x 788 x 998 x 642 = 103322533630368
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.
926 : 1, 2, 463, 926
221 : 1, 13, 17, 221
788 : 1, 2, 4, 197, 394, 788
998 : 1, 2, 499, 998
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 926,221,788,998,642, is 1.
Now, the common factors can be found like this.
926:2x 463
221:13x 17
788:2x 2x 197
998:2x 499
642:2x 3x 107
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 2 = 8
Therefore, the value for common factors is 8.
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 = 103322533630368/(1x8)
LCM = 103322533630368/8
LCM = 12915316703796
Thus, we can understand that the LCM of 926,221,788,998,642 is 12915316703796.
