Given numbers are 724,893,856,156
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 724,893,856,156 is 5395956072.
Find LCM of 724,893,856,156 with Prime Factorization
| 2 | 724, 893, 856, 156 |
| 2 | 362, 893, 428, 78 |
| 181, 893, 214, 39 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 181 x 893 x 214 x 39 = 5395956072
Therefore, the lowest common multiple of 724,893,856,156 is 5395956072.
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.
724 x 893 x 856 x 156 = 86335297152
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.
724 : 1, 2, 4, 181, 362, 724
893 : 1, 19, 47, 893
856 : 1, 2, 4, 8, 107, 214, 428, 856
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,893,856,156, is 1.
Now, the common factors can be found like this.
724:2x 2x 181
893:19x 47
856:2x 2x 2x 107
156:2x 2x 3x 13
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 2 = 16
Therefore, the value for common factors is 16.
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 = 86335297152/(1x16)
LCM = 86335297152/16
LCM = 5395956072
Thus, we can understand that the LCM of 724,893,856,156 is 5395956072.
