Given numbers are 642,746,621,321,592
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 642,746,621,321,592 is 14672560752.
Find LCM of 642,746,621,321,592 with Prime Factorization
| 2 | 642, 746, 621, 321, 592 |
| 3 | 321, 373, 621, 321, 296 |
| 107 | 107, 373, 207, 107, 296 |
| 1, 373, 207, 1, 296 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 107 x 1 x 373 x 207 x 1 x 296 = 14672560752
Therefore, the lowest common multiple of 642,746,621,321,592 is 14672560752.
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.
642 x 746 x 621 x 321 x 592 = 56518704016704
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.
642 : 1, 2, 3, 6, 107, 214, 321, 642
746 : 1, 2, 373, 746
621 : 1, 3, 9, 23, 27, 69, 207, 621
321 : 1, 3, 107, 321
592 : 1, 2, 4, 8, 16, 37, 74, 148, 296, 592
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,746,621,321,592, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
746:2x 373
621:3x 3x 3x 23
321:3x 107
592:2x 2x 2x 2x 37
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 3x 3x 107 = 3852
Therefore, the value for common factors is 3852.
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 = 56518704016704/(1x3852)
LCM = 56518704016704/3852
LCM = 14672560752
Thus, we can understand that the LCM of 642,746,621,321,592 is 14672560752.
