Given numbers are 564,851,621,805
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 564,851,621,805 is 151188660.
Find LCM of 564,851,621,805 with Prime Factorization
3 | 564, 851, 621, 805 |
23 | 188, 851, 207, 805 |
188, 37, 9, 35 |
Multiply the prime numbers at the bottom and the left side.
3 x 23 x 188 x 37 x 9 x 35 = 151188660
Therefore, the lowest common multiple of 564,851,621,805 is 151188660.
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.
564 x 851 x 621 x 805 = 239936403420
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.
564 : 1, 2, 3, 4, 6, 12, 47, 94, 141, 188, 282, 564
851 : 1, 23, 37, 851
621 : 1, 3, 9, 23, 27, 69, 207, 621
805 : 1, 5, 7, 23, 35, 115, 161, 805
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 564,851,621,805, is 1.
Now, the common factors can be found like this.
564:2x 2x 3x 47
851:23x 37
621:3x 3x 3x 23
805:5x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 23x 23 = 1587
Therefore, the value for common factors is 1587.
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 = 239936403420/(1x1587)
LCM = 239936403420/1587
LCM = 151188660
Thus, we can understand that the LCM of 564,851,621,805 is 151188660.
