Given numbers are 190,642,132,748
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 190,642,132,748 is 22810260.
Find LCM of 190,642,132,748 with Prime Factorization
| 2 | 190, 642, 132, 748 |
| 2 | 95, 321, 66, 374 |
| 3 | 95, 321, 33, 187 |
| 11 | 95, 107, 11, 187 |
| 95, 107, 1, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 95 x 107 x 1 x 17 = 22810260
Therefore, the lowest common multiple of 190,642,132,748 is 22810260.
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.
190 x 642 x 132 x 748 = 12043817280
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.
190 : 1, 2, 5, 10, 19, 38, 95, 190
642 : 1, 2, 3, 6, 107, 214, 321, 642
132 : 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, 132
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 190,642,132,748, is 2.
Now, the common factors can be found like this.
190:2x 5x 19
642:2x 3x 107
132:2x 2x 3x 11
748:2x 2x 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 2x 2x 3x 11 = 264
Therefore, the value for common factors is 264.
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 = 12043817280/(2x264)
LCM = 12043817280/528
LCM = 22810260
Thus, we can understand that the LCM of 190,642,132,748 is 22810260.
