Given numbers are 490,256,926,823,739
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 490,256,926,823,739 is 17661651633920.
Find LCM of 490,256,926,823,739 with Prime Factorization
| 2 | 490, 256, 926, 823, 739 |
| 245, 128, 463, 823, 739 |
Multiply the prime numbers at the bottom and the left side.
2 x 245 x 128 x 463 x 823 x 739 = 17661651633920
Therefore, the lowest common multiple of 490,256,926,823,739 is 17661651633920.
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.
490 x 256 x 926 x 823 x 739 = 70646606535680
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.
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
926 : 1, 2, 463, 926
823 : 1, 823
739 : 1, 739
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 490,256,926,823,739, is 1.
Now, the common factors can be found like this.
490:2x 5x 7x 7
256:2x 2x 2x 2x 2x 2x 2x 2
926:2x 463
823:823
739:739
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 70646606535680/(1x4)
LCM = 70646606535680/4
LCM = 17661651633920
Thus, we can understand that the LCM of 490,256,926,823,739 is 17661651633920.
