The LCM of 890,663,286,465 is 201213870.
Find LCM of 890,663,286,465 with Prime Factorization
| 2 | 890, 663, 286, 465 |
| 3 | 445, 663, 143, 465 |
| 5 | 445, 221, 143, 155 |
| 13 | 89, 221, 143, 31 |
| 89, 17, 11, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 89 x 17 x 11 x 31 = 201213870
Therefore, the lowest common multiple of 890,663,286,465 is 201213870.
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.
890 x 663 x 286 x 465 = 78473409300
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.
890 : 1, 2, 5, 10, 89, 178, 445, 890
663 : 1, 3, 13, 17, 39, 51, 221, 663
286 : 1, 2, 11, 13, 22, 26, 143, 286
465 : 1, 3, 5, 15, 31, 93, 155, 465
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 890,663,286,465, is 1.
Now, the common factors can be found like this.
890:2x 5x 89
663:3x 13x 17
286:2x 11x 13
465:3x 5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 13 = 390
Therefore, the value for common factors is 390.
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 = 78473409300/(1x390)
LCM = 78473409300/390
LCM = 201213870
Thus, we can understand that the LCM of 890,663,286,465 is 201213870.
