Given numbers are 161,130,460,943
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 161,130,460,943 is 1716260.
Find LCM of 161,130,460,943 with Prime Factorization
| 2 | 161, 130, 460, 943 |
| 5 | 161, 65, 230, 943 |
| 23 | 161, 13, 46, 943 |
| 7, 13, 2, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 23 x 7 x 13 x 2 x 41 = 1716260
Therefore, the lowest common multiple of 161,130,460,943 is 1716260.
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.
161 x 130 x 460 x 943 = 9079015400
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.
161 : 1, 7, 23, 161
130 : 1, 2, 5, 10, 13, 26, 65, 130
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
943 : 1, 23, 41, 943
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,130,460,943, is 1.
Now, the common factors can be found like this.
161:7x 23
130:2x 5x 13
460:2x 2x 5x 23
943:23x 41
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 23x 23 = 5290
Therefore, the value for common factors is 5290.
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 = 9079015400/(1x5290)
LCM = 9079015400/5290
LCM = 1716260
Thus, we can understand that the LCM of 161,130,460,943 is 1716260.
