Given numbers are 23,20,72,91,598
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 23,20,72,91,598 is 753480.
Find LCM of 23,20,72,91,598 with Prime Factorization
| 2 | 23, 20, 72, 91, 598 |
| 2 | 23, 10, 36, 91, 299 |
| 13 | 23, 5, 18, 91, 299 |
| 23 | 23, 5, 18, 7, 23 |
| 1, 5, 18, 7, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 23 x 1 x 5 x 18 x 7 x 1 = 753480
Therefore, the lowest common multiple of 23,20,72,91,598 is 753480.
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.
23 x 20 x 72 x 91 x 598 = 1802324160
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.
23 : 1, 23
20 : 1, 2, 4, 5, 10, 20
72 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
91 : 1, 7, 13, 91
598 : 1, 2, 13, 23, 26, 46, 299, 598
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 23,20,72,91,598, is 1.
Now, the common factors can be found like this.
23:23
20:2x 2x 5
72:2x 2x 2x 3x 3
91:7x 13
598:2x 13x 23
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 13x 23 = 2392
Therefore, the value for common factors is 2392.
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 = 1802324160/(1x2392)
LCM = 1802324160/2392
LCM = 753480
Thus, we can understand that the LCM of 23,20,72,91,598 is 753480.
