Given numbers are 830,871,508,780
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 830,871,508,780 is 550872660.
Find LCM of 830,871,508,780 with Prime Factorization
| 2 | 830, 871, 508, 780 |
| 2 | 415, 871, 254, 390 |
| 5 | 415, 871, 127, 195 |
| 13 | 83, 871, 127, 39 |
| 83, 67, 127, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 83 x 67 x 127 x 3 = 550872660
Therefore, the lowest common multiple of 830,871,508,780 is 550872660.
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.
830 x 871 x 508 x 780 = 286453783200
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.
830 : 1, 2, 5, 10, 83, 166, 415, 830
871 : 1, 13, 67, 871
508 : 1, 2, 4, 127, 254, 508
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 830,871,508,780, is 1.
Now, the common factors can be found like this.
830:2x 5x 83
871:13x 67
508:2x 2x 127
780:2x 2x 3x 5x 13
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 5x 13 = 520
Therefore, the value for common factors is 520.
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 = 286453783200/(1x520)
LCM = 286453783200/520
LCM = 550872660
Thus, we can understand that the LCM of 830,871,508,780 is 550872660.
