Given numbers are 399,403,767,809
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 399,403,767,809 is 7675001607.
Find LCM of 399,403,767,809 with Prime Factorization
| 13 | 399, 403, 767, 809 |
| 399, 31, 59, 809 |
Multiply the prime numbers at the bottom and the left side.
13 x 399 x 31 x 59 x 809 = 7675001607
Therefore, the lowest common multiple of 399,403,767,809 is 7675001607.
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 403 x 767 x 809 = 99775020891
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
403 : 1, 13, 31, 403
767 : 1, 13, 59, 767
809 : 1, 809
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,403,767,809, is 1.
Now, the common factors can be found like this.
399:3x 7x 19
403:13x 31
767:13x 59
809:809
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13 = 13
Therefore, the value for common factors is 13.
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 = 99775020891/(1x13)
LCM = 99775020891/13
LCM = 7675001607
Thus, we can understand that the LCM of 399,403,767,809 is 7675001607.
