Given numbers are 913,176,209,643
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 913,176,209,643 is 178465936.
Find LCM of 913,176,209,643 with Prime Factorization
| 11 | 913, 176, 209, 643 |
| 83, 16, 19, 643 |
Multiply the prime numbers at the bottom and the left side.
11 x 83 x 16 x 19 x 643 = 178465936
Therefore, the lowest common multiple of 913,176,209,643 is 178465936.
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.
913 x 176 x 209 x 643 = 21594378256
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.
913 : 1, 11, 83, 913
176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176
209 : 1, 11, 19, 209
643 : 1, 643
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 913,176,209,643, is 1.
Now, the common factors can be found like this.
913:11x 83
176:2x 2x 2x 2x 11
209:11x 19
643:643
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 11 = 121
Therefore, the value for common factors is 121.
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 = 21594378256/(1x121)
LCM = 21594378256/121
LCM = 178465936
Thus, we can understand that the LCM of 913,176,209,643 is 178465936.
