The LCM of 445,575,639,755,639 is 4937824575.
Find LCM of 445,575,639,755,639 with Prime Factorization
| 3 | 445, 575, 639, 755, 639 |
| 3 | 445, 575, 213, 755, 213 |
| 5 | 445, 575, 71, 755, 71 |
| 71 | 89, 115, 71, 151, 71 |
| 89, 115, 1, 151, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 71 x 89 x 115 x 1 x 151 x 1 = 4937824575
Therefore, the lowest common multiple of 445,575,639,755,639 is 4937824575.
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 575 x 639 x 755 x 639 = 78881747585625
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
575 : 1, 5, 23, 25, 115, 575
639 : 1, 3, 9, 71, 213, 639
755 : 1, 5, 151, 755
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 445,575,639,755,639, is 1.
Now, the common factors can be found like this.
445:5x 89
575:5x 5x 23
639:3x 3x 71
755:5x 151
639:3x 3x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 5x 71 = 15975
Therefore, the value for common factors is 15975.
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 = 78881747585625/(1x15975)
LCM = 78881747585625/15975
LCM = 4937824575
Thus, we can understand that the LCM of 445,575,639,755,639 is 4937824575.
