Given numbers are 811,663,545,660
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 811,663,545,660 is 12893878140.
Find LCM of 811,663,545,660 with Prime Factorization
3 | 811, 663, 545, 660 |
5 | 811, 221, 545, 220 |
811, 221, 109, 44 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 811 x 221 x 109 x 44 = 12893878140
Therefore, the lowest common multiple of 811,663,545,660 is 12893878140.
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.
811 x 663 x 545 x 660 = 193408172100
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.
811 : 1, 811
663 : 1, 3, 13, 17, 39, 51, 221, 663
545 : 1, 5, 109, 545
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 811,663,545,660, is 1.
Now, the common factors can be found like this.
811:811
663:3x 13x 17
545:5x 109
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.
3x 5 = 15
Therefore, the value for common factors is 15.
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 = 193408172100/(1x15)
LCM = 193408172100/15
LCM = 12893878140
Thus, we can understand that the LCM of 811,663,545,660 is 12893878140.
