Given numbers are 669,802,556,814,518
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 669,802,556,814,518 is 424949899836.
Find LCM of 669,802,556,814,518 with Prime Factorization
| 2 | 669, 802, 556, 814, 518 |
| 37 | 669, 401, 278, 407, 259 |
| 669, 401, 278, 11, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 37 x 669 x 401 x 278 x 11 x 7 = 424949899836
Therefore, the lowest common multiple of 669,802,556,814,518 is 424949899836.
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.
669 x 802 x 556 x 814 x 518 = 125785170351456
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.
669 : 1, 3, 223, 669
802 : 1, 2, 401, 802
556 : 1, 2, 4, 139, 278, 556
814 : 1, 2, 11, 22, 37, 74, 407, 814
518 : 1, 2, 7, 14, 37, 74, 259, 518
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,802,556,814,518, is 1.
Now, the common factors can be found like this.
669:3x 223
802:2x 401
556:2x 2x 139
814:2x 11x 37
518:2x 7x 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 2x 37 = 296
Therefore, the value for common factors is 296.
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 = 125785170351456/(1x296)
LCM = 125785170351456/296
LCM = 424949899836
Thus, we can understand that the LCM of 669,802,556,814,518 is 424949899836.
