Given numbers are 784,212,756,795,123
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 784,212,756,795,123 is 229990320.
Find LCM of 784,212,756,795,123 with Prime Factorization
| 2 | 784, 212, 756, 795, 123 |
| 2 | 392, 106, 378, 795, 123 |
| 3 | 196, 53, 189, 795, 123 |
| 7 | 196, 53, 63, 265, 41 |
| 53 | 28, 53, 9, 265, 41 |
| 28, 1, 9, 5, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 53 x 28 x 1 x 9 x 5 x 41 = 229990320
Therefore, the lowest common multiple of 784,212,756,795,123 is 229990320.
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.
784 x 212 x 756 x 795 x 123 = 12287002855680
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
212 : 1, 2, 4, 53, 106, 212
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
795 : 1, 3, 5, 15, 53, 159, 265, 795
123 : 1, 3, 41, 123
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,212,756,795,123, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
212:2x 2x 53
756:2x 2x 3x 3x 3x 7
795:3x 5x 53
123:3x 41
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 3x 3x 7x 53 = 53424
Therefore, the value for common factors is 53424.
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 = 12287002855680/(1x53424)
LCM = 12287002855680/53424
LCM = 229990320
Thus, we can understand that the LCM of 784,212,756,795,123 is 229990320.
