Given numbers are 668,120,616,814
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 668,120,616,814 is 57093960.
Find LCM of 668,120,616,814 with Prime Factorization
| 2 | 668, 120, 616, 814 |
| 2 | 334, 60, 308, 407 |
| 2 | 167, 30, 154, 407 |
| 11 | 167, 15, 77, 407 |
| 167, 15, 7, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 11 x 167 x 15 x 7 x 37 = 57093960
Therefore, the lowest common multiple of 668,120,616,814 is 57093960.
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.
668 x 120 x 616 x 814 = 40194147840
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.
668 : 1, 2, 4, 167, 334, 668
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
814 : 1, 2, 11, 22, 37, 74, 407, 814
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,120,616,814, is 2.
Now, the common factors can be found like this.
668:2x 2x 167
120:2x 2x 2x 3x 5
616:2x 2x 2x 7x 11
814:2x 11x 37
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 2x 2x 11 = 352
Therefore, the value for common factors is 352.
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 = 40194147840/(2x352)
LCM = 40194147840/704
LCM = 57093960
Thus, we can understand that the LCM of 668,120,616,814 is 57093960.
