Given numbers are 286,559,817,321
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 286,559,817,321 is 75005502.
Find LCM of 286,559,817,321 with Prime Factorization
| 13 | 286, 559, 817, 321 |
| 43 | 22, 43, 817, 321 |
| 22, 1, 19, 321 |
Multiply the prime numbers at the bottom and the left side.
13 x 43 x 22 x 1 x 19 x 321 = 75005502
Therefore, the lowest common multiple of 286,559,817,321 is 75005502.
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 559 x 817 x 321 = 41928075618
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
559 : 1, 13, 43, 559
817 : 1, 19, 43, 817
321 : 1, 3, 107, 321
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 286,559,817,321, is 1.
Now, the common factors can be found like this.
286:2x 11x 13
559:13x 43
817:19x 43
321:3x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 43 = 559
Therefore, the value for common factors is 559.
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 = 41928075618/(1x559)
LCM = 41928075618/559
LCM = 75005502
Thus, we can understand that the LCM of 286,559,817,321 is 75005502.
