Given numbers are 675,542,100,490
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 675,542,100,490 is 35853300.
Find LCM of 675,542,100,490 with Prime Factorization
| 2 | 675, 542, 100, 490 |
| 5 | 675, 271, 50, 245 |
| 5 | 135, 271, 10, 49 |
| 27, 271, 2, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 5 x 27 x 271 x 2 x 49 = 35853300
Therefore, the lowest common multiple of 675,542,100,490 is 35853300.
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.
675 x 542 x 100 x 490 = 17926650000
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.
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
542 : 1, 2, 271, 542
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 675,542,100,490, is 1.
Now, the common factors can be found like this.
675:3x 3x 3x 5x 5
542:2x 271
100:2x 2x 5x 5
490:2x 5x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 5x 5x 5 = 500
Therefore, the value for common factors is 500.
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 = 17926650000/(1x500)
LCM = 17926650000/500
LCM = 35853300
Thus, we can understand that the LCM of 675,542,100,490 is 35853300.
