Given numbers are 813,782,638,897,222
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 813,782,638,897,222 is 97551299274.
Find LCM of 813,782,638,897,222 with Prime Factorization
| 2 | 813, 782, 638, 897, 222 |
| 3 | 813, 391, 319, 897, 111 |
| 23 | 271, 391, 319, 299, 37 |
| 271, 17, 319, 13, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 271 x 17 x 319 x 13 x 37 = 97551299274
Therefore, the lowest common multiple of 813,782,638,897,222 is 97551299274.
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.
813 x 782 x 638 x 897 x 222 = 80772475798872
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.
813 : 1, 3, 271, 813
782 : 1, 2, 17, 23, 34, 46, 391, 782
638 : 1, 2, 11, 22, 29, 58, 319, 638
897 : 1, 3, 13, 23, 39, 69, 299, 897
222 : 1, 2, 3, 6, 37, 74, 111, 222
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,782,638,897,222, is 1.
Now, the common factors can be found like this.
813:3x 271
782:2x 17x 23
638:2x 11x 29
897:3x 13x 23
222:2x 3x 37
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 3x 3x 23 = 828
Therefore, the value for common factors is 828.
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 = 80772475798872/(1x828)
LCM = 80772475798872/828
LCM = 97551299274
Thus, we can understand that the LCM of 813,782,638,897,222 is 97551299274.
