Given numbers are 684,817,719
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 684,817,719 is 21147228.
Find LCM of 684,817,719 with Prime Factorization
19 | 684, 817, 719 |
36, 43, 719 |
Multiply the prime numbers at the bottom and the left side.
19 x 36 x 43 x 719 = 21147228
Therefore, the lowest common multiple of 684,817,719 is 21147228.
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.
684 x 817 x 719 = 401797332
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
817 : 1, 19, 43, 817
719 : 1, 719
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,817,719, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
817:19x 43
719:719
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19 = 19
Therefore, the value for common factors is 19.
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 = 401797332/(1x19)
LCM = 401797332/19
LCM = 21147228
Thus, we can understand that the LCM of 684,817,719 is 21147228.
