Given numbers are 872,428,559,506,390
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 872,428,559,506,390 is 197935572120.
Find LCM of 872,428,559,506,390 with Prime Factorization
| 2 | 872, 428, 559, 506, 390 |
| 2 | 436, 214, 559, 253, 195 |
| 13 | 218, 107, 559, 253, 195 |
| 218, 107, 43, 253, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 218 x 107 x 43 x 253 x 15 = 197935572120
Therefore, the lowest common multiple of 872,428,559,506,390 is 197935572120.
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.
872 x 428 x 559 x 506 x 390 = 41170599000960
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.
872 : 1, 2, 4, 8, 109, 218, 436, 872
428 : 1, 2, 4, 107, 214, 428
559 : 1, 13, 43, 559
506 : 1, 2, 11, 22, 23, 46, 253, 506
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 872,428,559,506,390, is 1.
Now, the common factors can be found like this.
872:2x 2x 2x 109
428:2x 2x 107
559:13x 43
506:2x 11x 23
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.
2x 2x 2x 2x 13 = 208
Therefore, the value for common factors is 208.
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 = 41170599000960/(1x208)
LCM = 41170599000960/208
LCM = 197935572120
Thus, we can understand that the LCM of 872,428,559,506,390 is 197935572120.
