Given numbers are 684,621,851,709
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 684,621,851,709 is 1238092668.
Find LCM of 684,621,851,709 with Prime Factorization
| 3 | 684, 621, 851, 709 |
| 3 | 228, 207, 851, 709 |
| 23 | 76, 69, 851, 709 |
| 76, 3, 37, 709 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 23 x 76 x 3 x 37 x 709 = 1238092668
Therefore, the lowest common multiple of 684,621,851,709 is 1238092668.
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 621 x 851 x 709 = 256285182276
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
621 : 1, 3, 9, 23, 27, 69, 207, 621
851 : 1, 23, 37, 851
709 : 1, 709
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,621,851,709, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
621:3x 3x 3x 23
851:23x 37
709:709
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 23 = 207
Therefore, the value for common factors is 207.
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 = 256285182276/(1x207)
LCM = 256285182276/207
LCM = 1238092668
Thus, we can understand that the LCM of 684,621,851,709 is 1238092668.
