Given numbers are 470,892,508,381
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 470,892,508,381 is 79865220.
Find LCM of 470,892,508,381 with Prime Factorization
| 2 | 470, 892, 508, 381 |
| 2 | 235, 446, 254, 381 |
| 127 | 235, 223, 127, 381 |
| 235, 223, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 127 x 235 x 223 x 1 x 3 = 79865220
Therefore, the lowest common multiple of 470,892,508,381 is 79865220.
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.
470 x 892 x 508 x 381 = 81143063520
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.
470 : 1, 2, 5, 10, 47, 94, 235, 470
892 : 1, 2, 4, 223, 446, 892
508 : 1, 2, 4, 127, 254, 508
381 : 1, 3, 127, 381
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 470,892,508,381, is 1.
Now, the common factors can be found like this.
470:2x 5x 47
892:2x 2x 223
508:2x 2x 127
381:3x 127
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 127 = 1016
Therefore, the value for common factors is 1016.
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 = 81143063520/(1x1016)
LCM = 81143063520/1016
LCM = 79865220
Thus, we can understand that the LCM of 470,892,508,381 is 79865220.
