Given numbers are 931,553,660,538,358
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 931,553,660,538,358 is 2337362213340.
Find LCM of 931,553,660,538,358 with Prime Factorization
| 2 | 931, 553, 660, 538, 358 |
| 7 | 931, 553, 330, 269, 179 |
| 133, 79, 330, 269, 179 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 133 x 79 x 330 x 269 x 179 = 2337362213340
Therefore, the lowest common multiple of 931,553,660,538,358 is 2337362213340.
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.
931 x 553 x 660 x 538 x 358 = 65446141973520
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.
931 : 1, 7, 19, 49, 133, 931
553 : 1, 7, 79, 553
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
538 : 1, 2, 269, 538
358 : 1, 2, 179, 358
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 931,553,660,538,358, is 1.
Now, the common factors can be found like this.
931:7x 7x 19
553:7x 79
660:2x 2x 3x 5x 11
538:2x 269
358:2x 179
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 7 = 28
Therefore, the value for common factors is 28.
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 = 65446141973520/(1x28)
LCM = 65446141973520/28
LCM = 2337362213340
Thus, we can understand that the LCM of 931,553,660,538,358 is 2337362213340.
