Given numbers are 253,110,391,748,903
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 253,110,391,748,903 is 77676060.
Find LCM of 253,110,391,748,903 with Prime Factorization
| 2 | 253, 110, 391, 748, 903 |
| 11 | 253, 55, 391, 374, 903 |
| 17 | 23, 5, 391, 34, 903 |
| 23 | 23, 5, 23, 2, 903 |
| 1, 5, 1, 2, 903 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 17 x 23 x 1 x 5 x 1 x 2 x 903 = 77676060
Therefore, the lowest common multiple of 253,110,391,748,903 is 77676060.
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.
253 x 110 x 391 x 748 x 903 = 7349864149320
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.
253 : 1, 11, 23, 253
110 : 1, 2, 5, 10, 11, 22, 55, 110
391 : 1, 17, 23, 391
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
903 : 1, 3, 7, 21, 43, 129, 301, 903
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 253,110,391,748,903, is 1.
Now, the common factors can be found like this.
253:11x 23
110:2x 5x 11
391:17x 23
748:2x 2x 11x 17
903:3x 7x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 11x 17x 23 = 94622
Therefore, the value for common factors is 94622.
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 = 7349864149320/(1x94622)
LCM = 7349864149320/94622
LCM = 77676060
Thus, we can understand that the LCM of 253,110,391,748,903 is 77676060.
