Find LCM of 440,442,770,763,808 with Prime Factorization
| 2 | 440, 442, 770, 763, 808 |
| 2 | 220, 221, 385, 763, 404 |
| 2 | 110, 221, 385, 763, 202 |
| 5 | 55, 221, 385, 763, 101 |
| 7 | 11, 221, 77, 763, 101 |
| 11 | 11, 221, 11, 109, 101 |
| 1, 221, 1, 109, 101 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 7 x 11 x 1 x 221 x 1 x 109 x 101 = 7493606120
Therefore, the lowest common multiple of 440,442,770,763,808 is 7493606120.
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.
440 x 442 x 770 x 763 x 808 = 92321227398400
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.
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
442 : 1, 2, 13, 17, 26, 34, 221, 442
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
763 : 1, 7, 109, 763
808 : 1, 2, 4, 8, 101, 202, 404, 808
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 440,442,770,763,808, is 1.
Now, the common factors can be found like this.
440:2x 2x 2x 5x 11
442:2x 13x 17
770:2x 5x 7x 11
763:7x 109
808:2x 2x 2x 101
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 2x 2x 5x 7x 11 = 12320
Therefore, the value for common factors is 12320.
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 = 92321227398400/(1x12320)
LCM = 92321227398400/12320
LCM = 7493606120
Thus, we can understand that the LCM of 440,442,770,763,808 is 7493606120.
