Given numbers are 684,994,931,704
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 684,994,931,704 is 418815936.
Find LCM of 684,994,931,704 with Prime Factorization
| 2 | 684, 994, 931, 704 |
| 2 | 342, 497, 931, 352 |
| 7 | 171, 497, 931, 176 |
| 19 | 171, 71, 133, 176 |
| 9, 71, 7, 176 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 19 x 9 x 71 x 7 x 176 = 418815936
Therefore, the lowest common multiple of 684,994,931,704 is 418815936.
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.
684 x 994 x 931 x 704 = 445620155904
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
994 : 1, 2, 7, 14, 71, 142, 497, 994
931 : 1, 7, 19, 49, 133, 931
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,994,931,704, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
994:2x 7x 71
931:7x 7x 19
704:2x 2x 2x 2x 2x 2x 11
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 7x 19 = 1064
Therefore, the value for common factors is 1064.
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 = 445620155904/(1x1064)
LCM = 445620155904/1064
LCM = 418815936
Thus, we can understand that the LCM of 684,994,931,704 is 418815936.
