Given numbers are 853,903,688,124
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 853,903,688,124 is 382048464.
Find LCM of 853,903,688,124 with Prime Factorization
| 2 | 853, 903, 688, 124 |
| 2 | 853, 903, 344, 62 |
| 43 | 853, 903, 172, 31 |
| 853, 21, 4, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 43 x 853 x 21 x 4 x 31 = 382048464
Therefore, the lowest common multiple of 853,903,688,124 is 382048464.
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.
853 x 903 x 688 x 124 = 65712335808
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.
853 : 1, 853
903 : 1, 3, 7, 21, 43, 129, 301, 903
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
124 : 1, 2, 4, 31, 62, 124
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 853,903,688,124, is 1.
Now, the common factors can be found like this.
853:853
903:3x 7x 43
688:2x 2x 2x 2x 43
124:2x 2x 31
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 43 = 172
Therefore, the value for common factors is 172.
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 = 65712335808/(1x172)
LCM = 65712335808/172
LCM = 382048464
Thus, we can understand that the LCM of 853,903,688,124 is 382048464.
