Given numbers are 605,817,390,949,758
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 605,817,390,949,758 is 1066679881410.
Find LCM of 605,817,390,949,758 with Prime Factorization
| 2 | 605, 817, 390, 949, 758 |
| 5 | 605, 817, 195, 949, 379 |
| 13 | 121, 817, 39, 949, 379 |
| 121, 817, 3, 73, 379 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 121 x 817 x 3 x 73 x 379 = 1066679881410
Therefore, the lowest common multiple of 605,817,390,949,758 is 1066679881410.
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.
605 x 817 x 390 x 949 x 758 = 138668384583300
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.
605 : 1, 5, 11, 55, 121, 605
817 : 1, 19, 43, 817
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
949 : 1, 13, 73, 949
758 : 1, 2, 379, 758
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,817,390,949,758, is 1.
Now, the common factors can be found like this.
605:5x 11x 11
817:19x 43
390:2x 3x 5x 13
949:13x 73
758:2x 379
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 13 = 130
Therefore, the value for common factors is 130.
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 = 138668384583300/(1x130)
LCM = 138668384583300/130
LCM = 1066679881410
Thus, we can understand that the LCM of 605,817,390,949,758 is 1066679881410.
