Given numbers are 578,434,949,899
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 578,434,949,899 is 3451848946.
Find LCM of 578,434,949,899 with Prime Factorization
| 2 | 578, 434, 949, 899 |
| 31 | 289, 217, 949, 899 |
| 289, 7, 949, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 31 x 289 x 7 x 949 x 29 = 3451848946
Therefore, the lowest common multiple of 578,434,949,899 is 3451848946.
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.
578 x 434 x 949 x 899 = 214014634652
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.
578 : 1, 2, 17, 34, 289, 578
434 : 1, 2, 7, 14, 31, 62, 217, 434
949 : 1, 13, 73, 949
899 : 1, 29, 31, 899
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,434,949,899, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
434:2x 7x 31
949:13x 73
899:29x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 31 = 62
Therefore, the value for common factors is 62.
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 = 214014634652/(1x62)
LCM = 214014634652/62
LCM = 3451848946
Thus, we can understand that the LCM of 578,434,949,899 is 3451848946.
