Given numbers are 667,843,686,930
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 667,843,686,930 is 59787338730.
Find LCM of 667,843,686,930 with Prime Factorization
| 2 | 667, 843, 686, 930 |
| 3 | 667, 843, 343, 465 |
| 667, 281, 343, 155 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 667 x 281 x 343 x 155 = 59787338730
Therefore, the lowest common multiple of 667,843,686,930 is 59787338730.
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.
667 x 843 x 686 x 930 = 358724032380
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.
667 : 1, 23, 29, 667
843 : 1, 3, 281, 843
686 : 1, 2, 7, 14, 49, 98, 343, 686
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 667,843,686,930, is 1.
Now, the common factors can be found like this.
667:23x 29
843:3x 281
686:2x 7x 7x 7
930:2x 3x 5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 358724032380/(1x6)
LCM = 358724032380/6
LCM = 59787338730
Thus, we can understand that the LCM of 667,843,686,930 is 59787338730.
