Find LCM of 545,104,418,621,720 with Prime Factorization
2 | 545, 104, 418, 621, 720 |
2 | 545, 52, 209, 621, 360 |
2 | 545, 26, 209, 621, 180 |
3 | 545, 13, 209, 621, 90 |
3 | 545, 13, 209, 207, 30 |
5 | 545, 13, 209, 69, 10 |
109, 13, 209, 69, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 5 x 109 x 13 x 209 x 69 x 2 = 14712881040
Therefore, the lowest common multiple of 545,104,418,621,720 is 14712881040.
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.
545 x 104 x 418 x 621 x 720 = 10593274348800
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.
545 : 1, 5, 109, 545
104 : 1, 2, 4, 8, 13, 26, 52, 104
418 : 1, 2, 11, 19, 22, 38, 209, 418
621 : 1, 3, 9, 23, 27, 69, 207, 621
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 545,104,418,621,720, is 1.
Now, the common factors can be found like this.
545:5x 109
104:2x 2x 2x 13
418:2x 11x 19
621:3x 3x 3x 23
720:2x 2x 2x 2x 3x 3x 5
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 3x 3x 5 = 720
Therefore, the value for common factors is 720.
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 = 10593274348800/(1x720)
LCM = 10593274348800/720
LCM = 14712881040
Thus, we can understand that the LCM of 545,104,418,621,720 is 14712881040.
