Given numbers are 917,130,901,520
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 917,130,901,520 is 429632840.
Find LCM of 917,130,901,520 with Prime Factorization
| 2 | 917, 130, 901, 520 |
| 5 | 917, 65, 901, 260 |
| 13 | 917, 13, 901, 52 |
| 917, 1, 901, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 917 x 1 x 901 x 4 = 429632840
Therefore, the lowest common multiple of 917,130,901,520 is 429632840.
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.
917 x 130 x 901 x 520 = 55852269200
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.
917 : 1, 7, 131, 917
130 : 1, 2, 5, 10, 13, 26, 65, 130
901 : 1, 17, 53, 901
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 917,130,901,520, is 1.
Now, the common factors can be found like this.
917:7x 131
130:2x 5x 13
901:17x 53
520:2x 2x 2x 5x 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 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 = 55852269200/(1x130)
LCM = 55852269200/130
LCM = 429632840
Thus, we can understand that the LCM of 917,130,901,520 is 429632840.
