Given numbers are 678,444,671,671
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 678,444,671,671 is 33665412.
Find LCM of 678,444,671,671 with Prime Factorization
| 2 | 678, 444, 671, 671 |
| 3 | 339, 222, 671, 671 |
| 11 | 113, 74, 671, 671 |
| 61 | 113, 74, 61, 61 |
| 113, 74, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 61 x 113 x 74 x 1 x 1 = 33665412
Therefore, the lowest common multiple of 678,444,671,671 is 33665412.
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.
678 x 444 x 671 x 671 = 135536948712
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.
678 : 1, 2, 3, 6, 113, 226, 339, 678
444 : 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444
671 : 1, 11, 61, 671
671 : 1, 11, 61, 671
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,444,671,671, is 1.
Now, the common factors can be found like this.
678:2x 3x 113
444:2x 2x 3x 37
671:11x 61
671:11x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 11x 61 = 4026
Therefore, the value for common factors is 4026.
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 = 135536948712/(1x4026)
LCM = 135536948712/4026
LCM = 33665412
Thus, we can understand that the LCM of 678,444,671,671 is 33665412.
