Given numbers are 964,138,246,690
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 964,138,246,690 is 13635780.
Find LCM of 964,138,246,690 with Prime Factorization
2 | 964, 138, 246, 690 |
3 | 482, 69, 123, 345 |
23 | 482, 23, 41, 115 |
482, 1, 41, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 482 x 1 x 41 x 5 = 13635780
Therefore, the lowest common multiple of 964,138,246,690 is 13635780.
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.
964 x 138 x 246 x 690 = 22580851680
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.
964 : 1, 2, 4, 241, 482, 964
138 : 1, 2, 3, 6, 23, 46, 69, 138
246 : 1, 2, 3, 6, 41, 82, 123, 246
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 964,138,246,690, is 2.
Now, the common factors can be found like this.
964:2x 2x 241
138:2x 3x 23
246:2x 3x 41
690:2x 3x 5x 23
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 3x 3x 23 = 828
Therefore, the value for common factors is 828.
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 = 22580851680/(2x828)
LCM = 22580851680/1656
LCM = 13635780
Thus, we can understand that the LCM of 964,138,246,690 is 13635780.
