Given numbers are 213,781,149,390
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 213,781,149,390 is 45383910.
Find LCM of 213,781,149,390 with Prime Factorization
| 3 | 213, 781, 149, 390 |
| 71 | 71, 781, 149, 130 |
| 1, 11, 149, 130 |
Multiply the prime numbers at the bottom and the left side.
3 x 71 x 1 x 11 x 149 x 130 = 45383910
Therefore, the lowest common multiple of 213,781,149,390 is 45383910.
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.
213 x 781 x 149 x 390 = 9666772830
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.
213 : 1, 3, 71, 213
781 : 1, 11, 71, 781
149 : 1, 149
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 213,781,149,390, is 1.
Now, the common factors can be found like this.
213:3x 71
781:11x 71
149:149
390:2x 3x 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.
3x 71 = 213
Therefore, the value for common factors is 213.
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 = 9666772830/(1x213)
LCM = 9666772830/213
LCM = 45383910
Thus, we can understand that the LCM of 213,781,149,390 is 45383910.
