Given numbers are 643,108,599,660
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 643,108,599,660 is 2287832580.
Find LCM of 643,108,599,660 with Prime Factorization
2 | 643, 108, 599, 660 |
2 | 643, 54, 599, 330 |
3 | 643, 27, 599, 165 |
643, 9, 599, 55 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 643 x 9 x 599 x 55 = 2287832580
Therefore, the lowest common multiple of 643,108,599,660 is 2287832580.
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.
643 x 108 x 599 x 660 = 27453990960
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.
643 : 1, 643
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
599 : 1, 599
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,108,599,660, is 1.
Now, the common factors can be found like this.
643:643
108:2x 2x 3x 3x 3
599:599
660:2x 2x 3x 5x 11
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 3 = 12
Therefore, the value for common factors is 12.
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 = 27453990960/(1x12)
LCM = 27453990960/12
LCM = 2287832580
Thus, we can understand that the LCM of 643,108,599,660 is 2287832580.
