The LCM of 805,705,812,417,138 is 1830154620.
Find LCM of 805,705,812,417,138 with Prime Factorization
| 2 | 805, 705, 812, 417, 138 |
| 3 | 805, 705, 406, 417, 69 |
| 5 | 805, 235, 406, 139, 23 |
| 7 | 161, 47, 406, 139, 23 |
| 23 | 23, 47, 58, 139, 23 |
| 1, 47, 58, 139, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 23 x 1 x 47 x 58 x 139 x 1 = 1830154620
Therefore, the lowest common multiple of 805,705,812,417,138 is 1830154620.
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.
805 x 705 x 812 x 417 x 138 = 26518940443800
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.
805 : 1, 5, 7, 23, 35, 115, 161, 805
705 : 1, 3, 5, 15, 47, 141, 235, 705
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
417 : 1, 3, 139, 417
138 : 1, 2, 3, 6, 23, 46, 69, 138
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 805,705,812,417,138, is 1.
Now, the common factors can be found like this.
805:5x 7x 23
705:3x 5x 47
812:2x 2x 7x 29
417:3x 139
138:2x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 7x 23 = 14490
Therefore, the value for common factors is 14490.
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 = 26518940443800/(1x14490)
LCM = 26518940443800/14490
LCM = 1830154620
Thus, we can understand that the LCM of 805,705,812,417,138 is 1830154620.
