Find LCM of 623,805,578,100,975 with Prime Factorization
2 | 623, 805, 578, 100, 975 |
5 | 623, 805, 289, 50, 975 |
5 | 623, 161, 289, 10, 195 |
7 | 623, 161, 289, 2, 39 |
89, 23, 289, 2, 39 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 5 x 7 x 89 x 23 x 289 x 2 x 39 = 16150215900
Therefore, the lowest common multiple of 623,805,578,100,975 is 16150215900.
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.
623 x 805 x 578 x 100 x 975 = 28262877825000
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.
623 : 1, 7, 89, 623
805 : 1, 5, 7, 23, 35, 115, 161, 805
578 : 1, 2, 17, 34, 289, 578
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 623,805,578,100,975, is 1.
Now, the common factors can be found like this.
623:7x 89
805:5x 7x 23
578:2x 17x 17
100:2x 2x 5x 5
975:3x 5x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 5x 7 = 1750
Therefore, the value for common factors is 1750.
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 = 28262877825000/(1x1750)
LCM = 28262877825000/1750
LCM = 16150215900
Thus, we can understand that the LCM of 623,805,578,100,975 is 16150215900.
