Given numbers are 578,745,942,894
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 578,745,942,894 is 202817310.
Find LCM of 578,745,942,894 with Prime Factorization
| 2 | 578, 745, 942, 894 |
| 3 | 289, 745, 471, 447 |
| 149 | 289, 745, 157, 149 |
| 289, 5, 157, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 149 x 289 x 5 x 157 x 1 = 202817310
Therefore, the lowest common multiple of 578,745,942,894 is 202817310.
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 745 x 942 x 894 = 362637350280
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
745 : 1, 5, 149, 745
942 : 1, 2, 3, 6, 157, 314, 471, 942
894 : 1, 2, 3, 6, 149, 298, 447, 894
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,745,942,894, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
745:5x 149
942:2x 3x 157
894:2x 3x 149
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 149 = 1788
Therefore, the value for common factors is 1788.
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 = 362637350280/(1x1788)
LCM = 362637350280/1788
LCM = 202817310
Thus, we can understand that the LCM of 578,745,942,894 is 202817310.
