Given numbers are 139,160,353,870
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 139,160,353,870 is 683012640.
Find LCM of 139,160,353,870 with Prime Factorization
| 2 | 139, 160, 353, 870 |
| 5 | 139, 80, 353, 435 |
| 139, 16, 353, 87 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 139 x 16 x 353 x 87 = 683012640
Therefore, the lowest common multiple of 139,160,353,870 is 683012640.
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.
139 x 160 x 353 x 870 = 6830126400
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.
139 : 1, 139
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
353 : 1, 353
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 139,160,353,870, is 1.
Now, the common factors can be found like this.
139:139
160:2x 2x 2x 2x 2x 5
353:353
870:2x 3x 5x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 6830126400/(1x10)
LCM = 6830126400/10
LCM = 683012640
Thus, we can understand that the LCM of 139,160,353,870 is 683012640.
