The LCM of 445,613,638,290 is 174036830.
Find LCM of 445,613,638,290 with Prime Factorization
| 2 | 445, 613, 638, 290 |
| 5 | 445, 613, 319, 145 |
| 29 | 89, 613, 319, 29 |
| 89, 613, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 29 x 89 x 613 x 11 x 1 = 174036830
Therefore, the lowest common multiple of 445,613,638,290 is 174036830.
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.
445 x 613 x 638 x 290 = 50470680700
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.
445 : 1, 5, 89, 445
613 : 1, 613
638 : 1, 2, 11, 22, 29, 58, 319, 638
290 : 1, 2, 5, 10, 29, 58, 145, 290
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 445,613,638,290, is 1.
Now, the common factors can be found like this.
445:5x 89
613:613
638:2x 11x 29
290:2x 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 5x 29 = 290
Therefore, the value for common factors is 290.
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 = 50470680700/(1x290)
LCM = 50470680700/290
LCM = 174036830
Thus, we can understand that the LCM of 445,613,638,290 is 174036830.
