Given numbers are 418,780,756,662,769
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 418,780,756,662,769 is 2614181710140.
Find LCM of 418,780,756,662,769 with Prime Factorization
| 2 | 418, 780, 756, 662, 769 |
| 2 | 209, 390, 378, 331, 769 |
| 3 | 209, 195, 189, 331, 769 |
| 209, 65, 63, 331, 769 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 209 x 65 x 63 x 331 x 769 = 2614181710140
Therefore, the lowest common multiple of 418,780,756,662,769 is 2614181710140.
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.
418 x 780 x 756 x 662 x 769 = 125480722086720
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.
418 : 1, 2, 11, 19, 22, 38, 209, 418
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
662 : 1, 2, 331, 662
769 : 1, 769
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,780,756,662,769, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
780:2x 2x 3x 5x 13
756:2x 2x 3x 3x 3x 7
662:2x 331
769:769
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 3 = 48
Therefore, the value for common factors is 48.
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 = 125480722086720/(1x48)
LCM = 125480722086720/48
LCM = 2614181710140
Thus, we can understand that the LCM of 418,780,756,662,769 is 2614181710140.
