Given numbers are 738,678,784,422,707
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 738,678,784,422,707 is 696666137328.
Find LCM of 738,678,784,422,707 with Prime Factorization
| 2 | 738, 678, 784, 422, 707 |
| 3 | 369, 339, 392, 211, 707 |
| 7 | 123, 113, 392, 211, 707 |
| 123, 113, 56, 211, 101 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 123 x 113 x 56 x 211 x 101 = 696666137328
Therefore, the lowest common multiple of 738,678,784,422,707 is 696666137328.
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.
738 x 678 x 784 x 422 x 707 = 117039911071104
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.
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
678 : 1, 2, 3, 6, 113, 226, 339, 678
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
422 : 1, 2, 211, 422
707 : 1, 7, 101, 707
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 738,678,784,422,707, is 1.
Now, the common factors can be found like this.
738:2x 3x 3x 41
678:2x 3x 113
784:2x 2x 2x 2x 7x 7
422:2x 211
707:7x 101
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 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 117039911071104/(1x168)
LCM = 117039911071104/168
LCM = 696666137328
Thus, we can understand that the LCM of 738,678,784,422,707 is 696666137328.
