Given numbers are 740,492,557,858,309
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 740,492,557,858,309 is 746732904060.
Find LCM of 740,492,557,858,309 with Prime Factorization
| 2 | 740, 492, 557, 858, 309 |
| 2 | 370, 246, 557, 429, 309 |
| 3 | 185, 123, 557, 429, 309 |
| 185, 41, 557, 143, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 185 x 41 x 557 x 143 x 103 = 746732904060
Therefore, the lowest common multiple of 740,492,557,858,309 is 746732904060.
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.
740 x 492 x 557 x 858 x 309 = 53764769092320
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.
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
557 : 1, 557
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
309 : 1, 3, 103, 309
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 740,492,557,858,309, is 1.
Now, the common factors can be found like this.
740:2x 2x 5x 37
492:2x 2x 3x 41
557:557
858:2x 3x 11x 13
309:3x 103
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 3 = 72
Therefore, the value for common factors is 72.
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 = 53764769092320/(1x72)
LCM = 53764769092320/72
LCM = 746732904060
Thus, we can understand that the LCM of 740,492,557,858,309 is 746732904060.
