Given numbers are 570,138,817
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 570,138,817 is 563730.
Find LCM of 570,138,817 with Prime Factorization
| 2 | 570, 138, 817 |
| 3 | 285, 69, 817 |
| 19 | 95, 23, 817 |
| 5, 23, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 5 x 23 x 43 = 563730
Therefore, the lowest common multiple of 570,138,817 is 563730.
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.
570 x 138 x 817 = 64265220
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.
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
138 : 1, 2, 3, 6, 23, 46, 69, 138
817 : 1, 19, 43, 817
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 570,138,817, is 1.
Now, the common factors can be found like this.
570:2x 3x 5x 19
138:2x 3x 23
817:19x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 19 = 114
Therefore, the value for common factors is 114.
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 = 64265220/(1x114)
LCM = 64265220/114
LCM = 563730
Thus, we can understand that the LCM of 570,138,817 is 563730.
