Given numbers are 361,921,286,154
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 361,921,286,154 is 665626962.
Find LCM of 361,921,286,154 with Prime Factorization
| 2 | 361, 921, 286, 154 |
| 11 | 361, 921, 143, 77 |
| 361, 921, 13, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 361 x 921 x 13 x 7 = 665626962
Therefore, the lowest common multiple of 361,921,286,154 is 665626962.
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 921 x 286 x 154 = 14643793164
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
921 : 1, 3, 307, 921
286 : 1, 2, 11, 13, 22, 26, 143, 286
154 : 1, 2, 7, 11, 14, 22, 77, 154
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 361,921,286,154, is 1.
Now, the common factors can be found like this.
361:19x 19
921:3x 307
286:2x 11x 13
154:2x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 14643793164/(1x22)
LCM = 14643793164/22
LCM = 665626962
Thus, we can understand that the LCM of 361,921,286,154 is 665626962.
