Given numbers are 981,780,594,417,346
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 981,780,594,417,346 is 202403118060.
Find LCM of 981,780,594,417,346 with Prime Factorization
| 2 | 981, 780, 594, 417, 346 |
| 3 | 981, 390, 297, 417, 173 |
| 3 | 327, 130, 99, 139, 173 |
| 109, 130, 33, 139, 173 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 109 x 130 x 33 x 139 x 173 = 202403118060
Therefore, the lowest common multiple of 981,780,594,417,346 is 202403118060.
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.
981 x 780 x 594 x 417 x 346 = 65578610251440
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.
981 : 1, 3, 9, 109, 327, 981
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
594 : 1, 2, 3, 6, 9, 11, 18, 22, 27, 33, 54, 66, 99, 198, 297, 594
417 : 1, 3, 139, 417
346 : 1, 2, 173, 346
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,780,594,417,346, is 1.
Now, the common factors can be found like this.
981:3x 3x 109
780:2x 2x 3x 5x 13
594:2x 3x 3x 3x 11
417:3x 139
346:2x 173
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 3x 3x 3x 3 = 324
Therefore, the value for common factors is 324.
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 = 65578610251440/(1x324)
LCM = 65578610251440/324
LCM = 202403118060
Thus, we can understand that the LCM of 981,780,594,417,346 is 202403118060.
