Find LCM of 988,820,462,553,312 with Prime Factorization
| 2 | 988, 820, 462, 553, 312 |
| 2 | 494, 410, 231, 553, 156 |
| 3 | 247, 205, 231, 553, 78 |
| 7 | 247, 205, 77, 553, 26 |
| 13 | 247, 205, 11, 79, 26 |
| 19, 205, 11, 79, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 13 x 19 x 205 x 11 x 79 x 2 = 7392304920
Therefore, the lowest common multiple of 988,820,462,553,312 is 7392304920.
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.
988 x 820 x 462 x 553 x 312 = 64579175781120
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.
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
553 : 1, 7, 79, 553
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,820,462,553,312, is 1.
Now, the common factors can be found like this.
988:2x 2x 13x 19
820:2x 2x 5x 41
462:2x 3x 7x 11
553:7x 79
312:2x 2x 2x 3x 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 2x 2x 2x 3x 7x 13 = 8736
Therefore, the value for common factors is 8736.
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 = 64579175781120/(1x8736)
LCM = 64579175781120/8736
LCM = 7392304920
Thus, we can understand that the LCM of 988,820,462,553,312 is 7392304920.
