Find LCM of 392,403,824,899,872 with Prime Factorization
| 2 | 392, 403, 824, 899, 872 |
| 2 | 196, 403, 412, 899, 436 |
| 2 | 98, 403, 206, 899, 218 |
| 31 | 49, 403, 103, 899, 109 |
| 49, 13, 103, 29, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 31 x 49 x 13 x 103 x 29 x 109 = 51434300008
Therefore, the lowest common multiple of 392,403,824,899,872 is 51434300008.
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.
392 x 403 x 824 x 899 x 872 = 102045651215872
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.
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
403 : 1, 13, 31, 403
824 : 1, 2, 4, 8, 103, 206, 412, 824
899 : 1, 29, 31, 899
872 : 1, 2, 4, 8, 109, 218, 436, 872
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,403,824,899,872, is 1.
Now, the common factors can be found like this.
392:2x 2x 2x 7x 7
403:13x 31
824:2x 2x 2x 103
899:29x 31
872:2x 2x 2x 109
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 2x 31 = 1984
Therefore, the value for common factors is 1984.
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 = 102045651215872/(1x1984)
LCM = 102045651215872/1984
LCM = 51434300008
Thus, we can understand that the LCM of 392,403,824,899,872 is 51434300008.
