Given numbers are 628,180,964,991,340
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 628,180,964,991,340 is 114739189020.
Find LCM of 628,180,964,991,340 with Prime Factorization
| 2 | 628, 180, 964, 991, 340 |
| 2 | 314, 90, 482, 991, 170 |
| 5 | 157, 45, 241, 991, 85 |
| 157, 9, 241, 991, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 157 x 9 x 241 x 991 x 17 = 114739189020
Therefore, the lowest common multiple of 628,180,964,991,340 is 114739189020.
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.
628 x 180 x 964 x 991 x 340 = 36716540486400
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.
628 : 1, 2, 4, 157, 314, 628
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
964 : 1, 2, 4, 241, 482, 964
991 : 1, 991
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,180,964,991,340, is 1.
Now, the common factors can be found like this.
628:2x 2x 157
180:2x 2x 3x 3x 5
964:2x 2x 241
991:991
340:2x 2x 5x 17
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 2x 2x 2x 5 = 320
Therefore, the value for common factors is 320.
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 = 36716540486400/(1x320)
LCM = 36716540486400/320
LCM = 114739189020
Thus, we can understand that the LCM of 628,180,964,991,340 is 114739189020.
