Given numbers are 280,681,388,550,724
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 280,681,388,550,724 is 184127281800.
Find LCM of 280,681,388,550,724 with Prime Factorization
| 2 | 280, 681, 388, 550, 724 |
| 2 | 140, 681, 194, 275, 362 |
| 5 | 70, 681, 97, 275, 181 |
| 14, 681, 97, 55, 181 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 14 x 681 x 97 x 55 x 181 = 184127281800
Therefore, the lowest common multiple of 280,681,388,550,724 is 184127281800.
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.
280 x 681 x 388 x 550 x 724 = 29460365088000
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.
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
681 : 1, 3, 227, 681
388 : 1, 2, 4, 97, 194, 388
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
724 : 1, 2, 4, 181, 362, 724
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 280,681,388,550,724, is 1.
Now, the common factors can be found like this.
280:2x 2x 2x 5x 7
681:3x 227
388:2x 2x 97
550:2x 5x 5x 11
724:2x 2x 181
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 5 = 160
Therefore, the value for common factors is 160.
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 = 29460365088000/(1x160)
LCM = 29460365088000/160
LCM = 184127281800
Thus, we can understand that the LCM of 280,681,388,550,724 is 184127281800.
