Given numbers are 426,660,714,870
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 426,660,714,870 is 161713860.
Find LCM of 426,660,714,870 with Prime Factorization
| 2 | 426, 660, 714, 870 |
| 3 | 213, 330, 357, 435 |
| 5 | 71, 110, 119, 145 |
| 71, 22, 119, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 71 x 22 x 119 x 29 = 161713860
Therefore, the lowest common multiple of 426,660,714,870 is 161713860.
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.
426 x 660 x 714 x 870 = 174650968800
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.
426 : 1, 2, 3, 6, 71, 142, 213, 426
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
6 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 426,660,714,870, is 6.
Now, the common factors can be found like this.
426:2x 3x 71
660:2x 2x 3x 5x 11
714:2x 3x 7x 17
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 2x 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 174650968800/(6x180)
LCM = 174650968800/1080
LCM = 161713860
Thus, we can understand that the LCM of 426,660,714,870 is 161713860.
