Given numbers are 598,805,820,220
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 598,805,820,220 is 18878860.
Find LCM of 598,805,820,220 with Prime Factorization
| 2 | 598, 805, 820, 220 |
| 2 | 299, 805, 410, 110 |
| 5 | 299, 805, 205, 55 |
| 23 | 299, 161, 41, 11 |
| 13, 7, 41, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 23 x 13 x 7 x 41 x 11 = 18878860
Therefore, the lowest common multiple of 598,805,820,220 is 18878860.
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.
598 x 805 x 820 x 220 = 86842756000
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.
598 : 1, 2, 13, 23, 26, 46, 299, 598
805 : 1, 5, 7, 23, 35, 115, 161, 805
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 598,805,820,220, is 1.
Now, the common factors can be found like this.
598:2x 13x 23
805:5x 7x 23
820:2x 2x 5x 41
220:2x 2x 5x 11
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 5x 5x 23 = 4600
Therefore, the value for common factors is 4600.
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 = 86842756000/(1x4600)
LCM = 86842756000/4600
LCM = 18878860
Thus, we can understand that the LCM of 598,805,820,220 is 18878860.
