Given numbers are 565,988,515,780
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 565,988,515,780 is 172489980.
Find LCM of 565,988,515,780 with Prime Factorization
| 2 | 565, 988, 515, 780 |
| 2 | 565, 494, 515, 390 |
| 5 | 565, 247, 515, 195 |
| 13 | 113, 247, 103, 39 |
| 113, 19, 103, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 113 x 19 x 103 x 3 = 172489980
Therefore, the lowest common multiple of 565,988,515,780 is 172489980.
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.
565 x 988 x 515 x 780 = 224236974000
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.
565 : 1, 5, 113, 565
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
515 : 1, 5, 103, 515
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 565,988,515,780, is 1.
Now, the common factors can be found like this.
565:5x 113
988:2x 2x 13x 19
515:5x 103
780:2x 2x 3x 5x 13
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 5x 5x 13 = 1300
Therefore, the value for common factors is 1300.
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 = 224236974000/(1x1300)
LCM = 224236974000/1300
LCM = 172489980
Thus, we can understand that the LCM of 565,988,515,780 is 172489980.
