Given numbers are 399,803,451,578,409
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 399,803,451,578,409 is 3105442155354.
Find LCM of 399,803,451,578,409 with Prime Factorization
| 11 | 399, 803, 451, 578, 409 |
| 399, 73, 41, 578, 409 |
Multiply the prime numbers at the bottom and the left side.
11 x 399 x 73 x 41 x 578 x 409 = 3105442155354
Therefore, the lowest common multiple of 399,803,451,578,409 is 3105442155354.
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.
399 x 803 x 451 x 578 x 409 = 34159863708894
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.
399 : 1, 3, 7, 19, 21, 57, 133, 399
803 : 1, 11, 73, 803
451 : 1, 11, 41, 451
578 : 1, 2, 17, 34, 289, 578
409 : 1, 409
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,803,451,578,409, is 1.
Now, the common factors can be found like this.
399:3x 7x 19
803:11x 73
451:11x 41
578:2x 17x 17
409:409
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 34159863708894/(1x11)
LCM = 34159863708894/11
LCM = 3105442155354
Thus, we can understand that the LCM of 399,803,451,578,409 is 3105442155354.
