Given numbers are 717,645,230,870
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 717,645,230,870 is 205642770.
Find LCM of 717,645,230,870 with Prime Factorization
2 | 717, 645, 230, 870 |
3 | 717, 645, 115, 435 |
5 | 239, 215, 115, 145 |
239, 43, 23, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 239 x 43 x 23 x 29 = 205642770
Therefore, the lowest common multiple of 717,645,230,870 is 205642770.
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.
717 x 645 x 230 x 870 = 92539246500
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.
717 : 1, 3, 239, 717
645 : 1, 3, 5, 15, 43, 129, 215, 645
230 : 1, 2, 5, 10, 23, 46, 115, 230
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 717,645,230,870, is 1.
Now, the common factors can be found like this.
717:3x 239
645:3x 5x 43
230:2x 5x 23
870:2x 3x 5x 29
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 3x 5x 5 = 450
Therefore, the value for common factors is 450.
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 = 92539246500/(1x450)
LCM = 92539246500/450
LCM = 205642770
Thus, we can understand that the LCM of 717,645,230,870 is 205642770.
