Given numbers are 29,57,90,70,904
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 29,57,90,70,904 is 156902760.
Find LCM of 29,57,90,70,904 with Prime Factorization
| 2 | 29, 57, 90, 70, 904 |
| 3 | 29, 57, 45, 35, 452 |
| 5 | 29, 19, 15, 35, 452 |
| 29, 19, 3, 7, 452 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 29 x 19 x 3 x 7 x 452 = 156902760
Therefore, the lowest common multiple of 29,57,90,70,904 is 156902760.
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.
29 x 57 x 90 x 70 x 904 = 9414165600
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.
29 : 1, 29
57 : 1, 3, 19, 57
90 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90
70 : 1, 2, 5, 7, 10, 14, 35, 70
904 : 1, 2, 4, 8, 113, 226, 452, 904
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 29,57,90,70,904, is 1.
Now, the common factors can be found like this.
29:29
57:3x 19
90:2x 3x 3x 5
70:2x 5x 7
904:2x 2x 2x 113
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 3x 5 = 60
Therefore, the value for common factors is 60.
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 = 9414165600/(1x60)
LCM = 9414165600/60
LCM = 156902760
Thus, we can understand that the LCM of 29,57,90,70,904 is 156902760.
