Given numbers are 998,913,817,670,631
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 998,913,817,670,631 is 157361157563830.
Find LCM of 998,913,817,670,631 with Prime Factorization
| 2 | 998, 913, 817, 670, 631 |
| 499, 913, 817, 335, 631 |
Multiply the prime numbers at the bottom and the left side.
2 x 499 x 913 x 817 x 335 x 631 = 157361157563830
Therefore, the lowest common multiple of 998,913,817,670,631 is 157361157563830.
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.
998 x 913 x 817 x 670 x 631 = 314722315127660
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.
998 : 1, 2, 499, 998
913 : 1, 11, 83, 913
817 : 1, 19, 43, 817
670 : 1, 2, 5, 10, 67, 134, 335, 670
631 : 1, 631
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 998,913,817,670,631, is 1.
Now, the common factors can be found like this.
998:2x 499
913:11x 83
817:19x 43
670:2x 5x 67
631:631
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 314722315127660/(1x2)
LCM = 314722315127660/2
LCM = 157361157563830
Thus, we can understand that the LCM of 998,913,817,670,631 is 157361157563830.
