Given numbers are 325,490,645,675,100
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 325,490,645,675,100 is 73955700.
Find LCM of 325,490,645,675,100 with Prime Factorization
| 2 | 325, 490, 645, 675, 100 |
| 3 | 325, 245, 645, 675, 50 |
| 5 | 325, 245, 215, 225, 50 |
| 5 | 65, 49, 43, 45, 10 |
| 13, 49, 43, 9, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 5 x 13 x 49 x 43 x 9 x 2 = 73955700
Therefore, the lowest common multiple of 325,490,645,675,100 is 73955700.
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.
325 x 490 x 645 x 675 x 100 = 6933346875000
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.
325 : 1, 5, 13, 25, 65, 325
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
645 : 1, 3, 5, 15, 43, 129, 215, 645
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 325,490,645,675,100, is 5.
Now, the common factors can be found like this.
325:5x 5x 13
490:2x 5x 7x 7
645:3x 5x 43
675:3x 3x 3x 5x 5
100:2x 2x 5x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 5x 5x 5x 5 = 18750
Therefore, the value for common factors is 18750.
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 = 6933346875000/(5x18750)
LCM = 6933346875000/93750
LCM = 73955700
Thus, we can understand that the LCM of 325,490,645,675,100 is 73955700.
