Given numbers are 220,623,818,838
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 220,623,818,838 is 23488109260.
Find LCM of 220,623,818,838 with Prime Factorization
| 2 | 220, 623, 818, 838 |
| 110, 623, 409, 419 |
Multiply the prime numbers at the bottom and the left side.
2 x 110 x 623 x 409 x 419 = 23488109260
Therefore, the lowest common multiple of 220,623,818,838 is 23488109260.
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.
220 x 623 x 818 x 838 = 93952437040
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.
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
623 : 1, 7, 89, 623
818 : 1, 2, 409, 818
838 : 1, 2, 419, 838
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,623,818,838, is 1.
Now, the common factors can be found like this.
220:2x 2x 5x 11
623:7x 89
818:2x 409
838:2x 419
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 93952437040/(1x4)
LCM = 93952437040/4
LCM = 23488109260
Thus, we can understand that the LCM of 220,623,818,838 is 23488109260.
