Given numbers are 328,902,865,641,578
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 328,902,865,641,578 is 578147309080.
Find LCM of 328,902,865,641,578 with Prime Factorization
| 2 | 328, 902, 865, 641, 578 |
| 41 | 164, 451, 865, 641, 289 |
| 4, 11, 865, 641, 289 |
Multiply the prime numbers at the bottom and the left side.
2 x 41 x 4 x 11 x 865 x 641 x 289 = 578147309080
Therefore, the lowest common multiple of 328,902,865,641,578 is 578147309080.
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.
328 x 902 x 865 x 641 x 578 = 94816158689120
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.
328 : 1, 2, 4, 8, 41, 82, 164, 328
902 : 1, 2, 11, 22, 41, 82, 451, 902
865 : 1, 5, 173, 865
641 : 1, 641
578 : 1, 2, 17, 34, 289, 578
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 328,902,865,641,578, is 1.
Now, the common factors can be found like this.
328:2x 2x 2x 41
902:2x 11x 41
865:5x 173
641:641
578:2x 17x 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 41 = 164
Therefore, the value for common factors is 164.
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 = 94816158689120/(1x164)
LCM = 94816158689120/164
LCM = 578147309080
Thus, we can understand that the LCM of 328,902,865,641,578 is 578147309080.
