Given numbers are 770,102,662,391,667
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 770,102,662,391,667 is 8669912790.
Find LCM of 770,102,662,391,667 with Prime Factorization
| 2 | 770, 102, 662, 391, 667 |
| 17 | 385, 51, 331, 391, 667 |
| 23 | 385, 3, 331, 23, 667 |
| 385, 3, 331, 1, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 23 x 385 x 3 x 331 x 1 x 29 = 8669912790
Therefore, the lowest common multiple of 770,102,662,391,667 is 8669912790.
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.
770 x 102 x 662 x 391 x 667 = 13559743603560
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.
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
102 : 1, 2, 3, 6, 17, 34, 51, 102
662 : 1, 2, 331, 662
391 : 1, 17, 23, 391
667 : 1, 23, 29, 667
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,102,662,391,667, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
102:2x 3x 17
662:2x 331
391:17x 23
667:23x 29
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 17x 23 = 1564
Therefore, the value for common factors is 1564.
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 = 13559743603560/(1x1564)
LCM = 13559743603560/1564
LCM = 8669912790
Thus, we can understand that the LCM of 770,102,662,391,667 is 8669912790.
