Given numbers are 955,612,399,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 955,612,399,442 is 1010531340.
Find LCM of 955,612,399,442 with Prime Factorization
| 2 | 955, 612, 399, 442 |
| 3 | 955, 306, 399, 221 |
| 17 | 955, 102, 133, 221 |
| 955, 6, 133, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 955 x 6 x 133 x 13 = 1010531340
Therefore, the lowest common multiple of 955,612,399,442 is 1010531340.
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.
955 x 612 x 399 x 442 = 103074196680
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.
955 : 1, 5, 191, 955
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
399 : 1, 3, 7, 19, 21, 57, 133, 399
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 955,612,399,442, is 1.
Now, the common factors can be found like this.
955:5x 191
612:2x 2x 3x 3x 17
399:3x 7x 19
442:2x 13x 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 = 103074196680/(1x102)
LCM = 103074196680/102
LCM = 1010531340
Thus, we can understand that the LCM of 955,612,399,442 is 1010531340.
