Given numbers are 286,972,176,209,719
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 286,972,176,209,719 is 7595297424.
Find LCM of 286,972,176,209,719 with Prime Factorization
| 2 | 286, 972, 176, 209, 719 |
| 2 | 143, 486, 88, 209, 719 |
| 11 | 143, 243, 44, 209, 719 |
| 13, 243, 4, 19, 719 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 13 x 243 x 4 x 19 x 719 = 7595297424
Therefore, the lowest common multiple of 286,972,176,209,719 is 7595297424.
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.
286 x 972 x 176 x 209 x 719 = 7352247906432
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.
286 : 1, 2, 11, 13, 22, 26, 143, 286
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176
209 : 1, 11, 19, 209
719 : 1, 719
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 286,972,176,209,719, is 1.
Now, the common factors can be found like this.
286:2x 11x 13
972:2x 2x 3x 3x 3x 3x 3
176:2x 2x 2x 2x 11
209:11x 19
719:719
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 2x 11x 11 = 968
Therefore, the value for common factors is 968.
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 = 7352247906432/(1x968)
LCM = 7352247906432/968
LCM = 7595297424
Thus, we can understand that the LCM of 286,972,176,209,719 is 7595297424.
