Given numbers are 548,585,462,705
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 548,585,462,705 is 1160179020.
Find LCM of 548,585,462,705 with Prime Factorization
| 2 | 548, 585, 462, 705 |
| 3 | 274, 585, 231, 705 |
| 5 | 274, 195, 77, 235 |
| 274, 39, 77, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 274 x 39 x 77 x 47 = 1160179020
Therefore, the lowest common multiple of 548,585,462,705 is 1160179020.
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.
548 x 585 x 462 x 705 = 104416111800
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.
548 : 1, 2, 4, 137, 274, 548
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
705 : 1, 3, 5, 15, 47, 141, 235, 705
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 548,585,462,705, is 1.
Now, the common factors can be found like this.
548:2x 2x 137
585:3x 3x 5x 13
462:2x 3x 7x 11
705:3x 5x 47
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 5 = 90
Therefore, the value for common factors is 90.
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 = 104416111800/(1x90)
LCM = 104416111800/90
LCM = 1160179020
Thus, we can understand that the LCM of 548,585,462,705 is 1160179020.
