Given numbers are 542,704,370,460
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 542,704,370,460 is 811785920.
Find LCM of 542,704,370,460 with Prime Factorization
| 2 | 542, 704, 370, 460 |
| 2 | 271, 352, 185, 230 |
| 5 | 271, 176, 185, 115 |
| 271, 176, 37, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 271 x 176 x 37 x 23 = 811785920
Therefore, the lowest common multiple of 542,704,370,460 is 811785920.
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.
542 x 704 x 370 x 460 = 64942873600
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.
542 : 1, 2, 271, 542
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
370 : 1, 2, 5, 10, 37, 74, 185, 370
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 542,704,370,460, is 2.
Now, the common factors can be found like this.
542:2x 271
704:2x 2x 2x 2x 2x 2x 11
370:2x 5x 37
460:2x 2x 5x 23
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 5 = 40
Therefore, the value for common factors is 40.
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 = 64942873600/(2x40)
LCM = 64942873600/80
LCM = 811785920
Thus, we can understand that the LCM of 542,704,370,460 is 811785920.
