Given numbers are 690,676,894,179
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 690,676,894,179 is 6220210620.
Find LCM of 690,676,894,179 with Prime Factorization
| 2 | 690, 676, 894, 179 |
| 3 | 345, 338, 447, 179 |
| 115, 338, 149, 179 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 115 x 338 x 149 x 179 = 6220210620
Therefore, the lowest common multiple of 690,676,894,179 is 6220210620.
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.
690 x 676 x 894 x 179 = 74642527440
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.
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
894 : 1, 2, 3, 6, 149, 298, 447, 894
179 : 1, 179
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,676,894,179, is 1.
Now, the common factors can be found like this.
690:2x 3x 5x 23
676:2x 2x 13x 13
894:2x 3x 149
179:179
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 3 = 12
Therefore, the value for common factors is 12.
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 = 74642527440/(1x12)
LCM = 74642527440/12
LCM = 6220210620
Thus, we can understand that the LCM of 690,676,894,179 is 6220210620.
