Given numbers are 90,30,79,52,104
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 90,30,79,52,104 is 369720.
Find LCM of 90,30,79,52,104 with Prime Factorization
| 2 | 90, 30, 79, 52, 104 |
| 2 | 45, 15, 79, 26, 52 |
| 3 | 45, 15, 79, 13, 26 |
| 5 | 5, 15, 79, 13, 26 |
| 13 | 1, 3, 79, 13, 26 |
| 1, 3, 79, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 1 x 3 x 79 x 1 x 2 = 369720
Therefore, the lowest common multiple of 90,30,79,52,104 is 369720.
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.
90 x 30 x 79 x 52 x 104 = 1153526400
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.
90 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90
30 : 1, 2, 3, 5, 6, 10, 15, 30
79 : 1, 79
52 : 1, 2, 4, 13, 26, 52
104 : 1, 2, 4, 8, 13, 26, 52, 104
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 90,30,79,52,104, is 1.
Now, the common factors can be found like this.
90:2x 3x 3x 5
30:2x 3x 5
79:79
52:2x 2x 13
104:2x 2x 2x 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 2x 2x 2x 3x 5x 13 = 3120
Therefore, the value for common factors is 3120.
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 = 1153526400/(1x3120)
LCM = 1153526400/3120
LCM = 369720
Thus, we can understand that the LCM of 90,30,79,52,104 is 369720.
