Given numbers are 361,456,999,403,778
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 361,456,999,403,778 is 452290352904.
Find LCM of 361,456,999,403,778 with Prime Factorization
| 2 | 361, 456, 999, 403, 778 |
| 3 | 361, 228, 999, 403, 389 |
| 19 | 361, 76, 333, 403, 389 |
| 19, 4, 333, 403, 389 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 19 x 4 x 333 x 403 x 389 = 452290352904
Therefore, the lowest common multiple of 361,456,999,403,778 is 452290352904.
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.
361 x 456 x 999 x 403 x 778 = 51561100231056
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.
361 : 1, 19, 361
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
999 : 1, 3, 9, 27, 37, 111, 333, 999
403 : 1, 13, 31, 403
778 : 1, 2, 389, 778
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 361,456,999,403,778, is 1.
Now, the common factors can be found like this.
361:19x 19
456:2x 2x 2x 3x 19
999:3x 3x 3x 37
403:13x 31
778:2x 389
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 19 = 114
Therefore, the value for common factors is 114.
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 = 51561100231056/(1x114)
LCM = 51561100231056/114
LCM = 452290352904
Thus, we can understand that the LCM of 361,456,999,403,778 is 452290352904.
