Find LCM of 541,817,644,667,980 with Prime Factorization
| 2 | 541, 817, 644, 667, 980 |
| 2 | 541, 817, 322, 667, 490 |
| 7 | 541, 817, 161, 667, 245 |
| 23 | 541, 817, 23, 667, 35 |
| 541, 817, 1, 29, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 23 x 541 x 817 x 1 x 29 x 35 = 288915759020
Therefore, the lowest common multiple of 541,817,644,667,980 is 288915759020.
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.
541 x 817 x 644 x 667 x 980 = 186061748808880
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.
541 : 1, 541
817 : 1, 19, 43, 817
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
667 : 1, 23, 29, 667
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 541,817,644,667,980, is 1.
Now, the common factors can be found like this.
541:541
817:19x 43
644:2x 2x 7x 23
667:23x 29
980:2x 2x 5x 7x 7
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 7x 23 = 644
Therefore, the value for common factors is 644.
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 = 186061748808880/(1x644)
LCM = 186061748808880/644
LCM = 288915759020
Thus, we can understand that the LCM of 541,817,644,667,980 is 288915759020.
