Given numbers are 465,781,822,213,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 465,781,822,213,638 is 2885709090.
Find LCM of 465,781,822,213,638 with Prime Factorization
| 2 | 465, 781, 822, 213, 638 |
| 3 | 465, 781, 411, 213, 319 |
| 11 | 155, 781, 137, 71, 319 |
| 71 | 155, 71, 137, 71, 29 |
| 155, 1, 137, 1, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 71 x 155 x 1 x 137 x 1 x 29 = 2885709090
Therefore, the lowest common multiple of 465,781,822,213,638 is 2885709090.
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.
465 x 781 x 822 x 213 x 638 = 40567298387220
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.
465 : 1, 3, 5, 15, 31, 93, 155, 465
781 : 1, 11, 71, 781
822 : 1, 2, 3, 6, 137, 274, 411, 822
213 : 1, 3, 71, 213
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 465,781,822,213,638, is 1.
Now, the common factors can be found like this.
465:3x 5x 31
781:11x 71
822:2x 3x 137
213:3x 71
638:2x 11x 29
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 3x 11x 71 = 14058
Therefore, the value for common factors is 14058.
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 = 40567298387220/(1x14058)
LCM = 40567298387220/14058
LCM = 2885709090
Thus, we can understand that the LCM of 465,781,822,213,638 is 2885709090.
