Given numbers are 260,784,917,818,828
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 260,784,917,818,828 is 565189868880.
Find LCM of 260,784,917,818,828 with Prime Factorization
| 2 | 260, 784, 917, 818, 828 |
| 2 | 130, 392, 917, 409, 414 |
| 7 | 65, 196, 917, 409, 207 |
| 65, 28, 131, 409, 207 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 65 x 28 x 131 x 409 x 207 = 565189868880
Therefore, the lowest common multiple of 260,784,917,818,828 is 565189868880.
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.
260 x 784 x 917 x 818 x 828 = 126602530629120
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.
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
917 : 1, 7, 131, 917
818 : 1, 2, 409, 818
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 260,784,917,818,828, is 1.
Now, the common factors can be found like this.
260:2x 2x 5x 13
784:2x 2x 2x 2x 7x 7
917:7x 131
818:2x 409
828:2x 2x 3x 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 2x 2x 2x 2x 7 = 224
Therefore, the value for common factors is 224.
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 = 126602530629120/(1x224)
LCM = 126602530629120/224
LCM = 565189868880
Thus, we can understand that the LCM of 260,784,917,818,828 is 565189868880.
