Given numbers are 366,624,420,578
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 366,624,420,578 is 385017360.
Find LCM of 366,624,420,578 with Prime Factorization
| 2 | 366, 624, 420, 578 |
| 2 | 183, 312, 210, 289 |
| 3 | 183, 156, 105, 289 |
| 61, 52, 35, 289 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 61 x 52 x 35 x 289 = 385017360
Therefore, the lowest common multiple of 366,624,420,578 is 385017360.
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.
366 x 624 x 420 x 578 = 55442499840
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.
366 : 1, 2, 3, 6, 61, 122, 183, 366
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
578 : 1, 2, 17, 34, 289, 578
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 366,624,420,578, is 2.
Now, the common factors can be found like this.
366:2x 3x 61
624:2x 2x 2x 2x 3x 13
420:2x 2x 3x 5x 7
578:2x 17x 17
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 3x 3 = 72
Therefore, the value for common factors is 72.
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 = 55442499840/(2x72)
LCM = 55442499840/144
LCM = 385017360
Thus, we can understand that the LCM of 366,624,420,578 is 385017360.
