Given numbers are 692,442,193,945,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 692,442,193,945,561 is 306817531020.
Find LCM of 692,442,193,945,561 with Prime Factorization
| 2 | 692, 442, 193, 945, 561 |
| 3 | 346, 221, 193, 945, 561 |
| 17 | 346, 221, 193, 315, 187 |
| 346, 13, 193, 315, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 346 x 13 x 193 x 315 x 11 = 306817531020
Therefore, the lowest common multiple of 692,442,193,945,561 is 306817531020.
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.
692 x 442 x 193 x 945 x 561 = 31295388164040
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.
692 : 1, 2, 4, 173, 346, 692
442 : 1, 2, 13, 17, 26, 34, 221, 442
193 : 1, 193
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 692,442,193,945,561, is 1.
Now, the common factors can be found like this.
692:2x 2x 173
442:2x 13x 17
193:193
945:3x 3x 3x 5x 7
561:3x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 17 = 102
Therefore, the value for common factors is 102.
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 = 31295388164040/(1x102)
LCM = 31295388164040/102
LCM = 306817531020
Thus, we can understand that the LCM of 692,442,193,945,561 is 306817531020.
