Find LCM of 460,618,139,445,644 with Prime Factorization
| 2 | 460, 618, 139, 445, 644 |
| 2 | 230, 309, 139, 445, 322 |
| 5 | 115, 309, 139, 445, 161 |
| 23 | 23, 309, 139, 89, 161 |
| 1, 309, 139, 89, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 23 x 1 x 309 x 139 x 89 x 7 = 12308897580
Therefore, the lowest common multiple of 460,618,139,445,644 is 12308897580.
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.
460 x 618 x 139 x 445 x 644 = 11324185773600
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.
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
618 : 1, 2, 3, 6, 103, 206, 309, 618
139 : 1, 139
445 : 1, 5, 89, 445
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 460,618,139,445,644, is 1.
Now, the common factors can be found like this.
460:2x 2x 5x 23
618:2x 3x 103
139:139
445:5x 89
644:2x 2x 7x 23
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 5x 23 = 920
Therefore, the value for common factors is 920.
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 = 11324185773600/(1x920)
LCM = 11324185773600/920
LCM = 12308897580
Thus, we can understand that the LCM of 460,618,139,445,644 is 12308897580.
