Given numbers are 256,697,578,511,553
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 256,697,578,511,553 is 122453063936.
Find LCM of 256,697,578,511,553 with Prime Factorization
| 2 | 256, 697, 578, 511, 553 |
| 7 | 128, 697, 289, 511, 553 |
| 17 | 128, 697, 289, 73, 79 |
| 128, 41, 17, 73, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 17 x 128 x 41 x 17 x 73 x 79 = 122453063936
Therefore, the lowest common multiple of 256,697,578,511,553 is 122453063936.
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.
256 x 697 x 578 x 511 x 553 = 29143829216768
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.
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
697 : 1, 17, 41, 697
578 : 1, 2, 17, 34, 289, 578
511 : 1, 7, 73, 511
553 : 1, 7, 79, 553
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 256,697,578,511,553, is 1.
Now, the common factors can be found like this.
256:2x 2x 2x 2x 2x 2x 2x 2
697:17x 41
578:2x 17x 17
511:7x 73
553:7x 79
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 17 = 238
Therefore, the value for common factors is 238.
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 = 29143829216768/(1x238)
LCM = 29143829216768/238
LCM = 122453063936
Thus, we can understand that the LCM of 256,697,578,511,553 is 122453063936.
