Given numbers are 561,956,156,807
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,956,156,807 is 1875497052.
Find LCM of 561,956,156,807 with Prime Factorization
| 2 | 561, 956, 156, 807 |
| 2 | 561, 478, 78, 807 |
| 3 | 561, 239, 39, 807 |
| 187, 239, 13, 269 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 187 x 239 x 13 x 269 = 1875497052
Therefore, the lowest common multiple of 561,956,156,807 is 1875497052.
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.
561 x 956 x 156 x 807 = 67517893872
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
956 : 1, 2, 4, 239, 478, 956
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
807 : 1, 3, 269, 807
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,956,156,807, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
956:2x 2x 239
156:2x 2x 3x 13
807:3x 269
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 3x 3 = 36
Therefore, the value for common factors is 36.
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 = 67517893872/(1x36)
LCM = 67517893872/36
LCM = 1875497052
Thus, we can understand that the LCM of 561,956,156,807 is 1875497052.
