Given numbers are 156,538,668,818,896
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 156,538,668,818,896 is 642043828608.
Find LCM of 156,538,668,818,896 with Prime Factorization
| 2 | 156, 538, 668, 818, 896 |
| 2 | 78, 269, 334, 409, 448 |
| 39, 269, 167, 409, 224 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 39 x 269 x 167 x 409 x 224 = 642043828608
Therefore, the lowest common multiple of 156,538,668,818,896 is 642043828608.
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.
156 x 538 x 668 x 818 x 896 = 41090805030912
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.
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
538 : 1, 2, 269, 538
668 : 1, 2, 4, 167, 334, 668
818 : 1, 2, 409, 818
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 156,538,668,818,896, is 2.
Now, the common factors can be found like this.
156:2x 2x 3x 13
538:2x 269
668:2x 2x 167
818:2x 409
896:2x 2x 2x 2x 2x 2x 2x 7
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 2 = 32
Therefore, the value for common factors is 32.
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 = 41090805030912/(2x32)
LCM = 41090805030912/64
LCM = 642043828608
Thus, we can understand that the LCM of 156,538,668,818,896 is 642043828608.
