Given numbers are 195,655,507,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 195,655,507,442 is 11290890.
Find LCM of 195,655,507,442 with Prime Factorization
| 3 | 195, 655, 507, 442 |
| 5 | 65, 655, 169, 442 |
| 13 | 13, 131, 169, 442 |
| 1, 131, 13, 34 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 13 x 1 x 131 x 13 x 34 = 11290890
Therefore, the lowest common multiple of 195,655,507,442 is 11290890.
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.
195 x 655 x 507 x 442 = 28622406150
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.
195 : 1, 3, 5, 13, 15, 39, 65, 195
655 : 1, 5, 131, 655
507 : 1, 3, 13, 39, 169, 507
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 195,655,507,442, is 1.
Now, the common factors can be found like this.
195:3x 5x 13
655:5x 131
507:3x 13x 13
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.
3x 5x 13x 13 = 2535
Therefore, the value for common factors is 2535.
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 = 28622406150/(1x2535)
LCM = 28622406150/2535
LCM = 11290890
Thus, we can understand that the LCM of 195,655,507,442 is 11290890.
