Given numbers are 361,644,418,909,854
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 361,644,418,909,854 is 141801058476.
Find LCM of 361,644,418,909,854 with Prime Factorization
| 2 | 361, 644, 418, 909, 854 |
| 7 | 361, 322, 209, 909, 427 |
| 19 | 361, 46, 209, 909, 61 |
| 19, 46, 11, 909, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 19 x 19 x 46 x 11 x 909 x 61 = 141801058476
Therefore, the lowest common multiple of 361,644,418,909,854 is 141801058476.
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 644 x 418 x 909 x 854 = 75438163109232
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
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
418 : 1, 2, 11, 19, 22, 38, 209, 418
909 : 1, 3, 9, 101, 303, 909
854 : 1, 2, 7, 14, 61, 122, 427, 854
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 361,644,418,909,854, is 1.
Now, the common factors can be found like this.
361:19x 19
644:2x 2x 7x 23
418:2x 11x 19
909:3x 3x 101
854:2x 7x 61
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 7x 19 = 532
Therefore, the value for common factors is 532.
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 = 75438163109232/(1x532)
LCM = 75438163109232/532
LCM = 141801058476
Thus, we can understand that the LCM of 361,644,418,909,854 is 141801058476.
