Given numbers are 802,551,638,662
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 802,551,638,662 is 1608965182.
Find LCM of 802,551,638,662 with Prime Factorization
| 2 | 802, 551, 638, 662 |
| 29 | 401, 551, 319, 331 |
| 401, 19, 11, 331 |
Multiply the prime numbers at the bottom and the left side.
2 x 29 x 401 x 19 x 11 x 331 = 1608965182
Therefore, the lowest common multiple of 802,551,638,662 is 1608965182.
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.
802 x 551 x 638 x 662 = 186639961112
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.
802 : 1, 2, 401, 802
551 : 1, 19, 29, 551
638 : 1, 2, 11, 22, 29, 58, 319, 638
662 : 1, 2, 331, 662
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 802,551,638,662, is 1.
Now, the common factors can be found like this.
802:2x 401
551:19x 29
638:2x 11x 29
662:2x 331
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 29 = 116
Therefore, the value for common factors is 116.
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 = 186639961112/(1x116)
LCM = 186639961112/116
LCM = 1608965182
Thus, we can understand that the LCM of 802,551,638,662 is 1608965182.
