Given numbers are 724,139,905,571,855
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 724,139,905,571,855 is 49130998380.
Find LCM of 724,139,905,571,855 with Prime Factorization
| 5 | 724, 139, 905, 571, 855 |
| 181 | 724, 139, 181, 571, 171 |
| 4, 139, 1, 571, 171 |
Multiply the prime numbers at the bottom and the left side.
5 x 181 x 4 x 139 x 1 x 571 x 171 = 49130998380
Therefore, the lowest common multiple of 724,139,905,571,855 is 49130998380.
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.
724 x 139 x 905 x 571 x 855 = 44463553533900
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.
724 : 1, 2, 4, 181, 362, 724
139 : 1, 139
905 : 1, 5, 181, 905
571 : 1, 571
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,139,905,571,855, is 1.
Now, the common factors can be found like this.
724:2x 2x 181
139:139
905:5x 181
571:571
855:3x 3x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 181 = 905
Therefore, the value for common factors is 905.
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 = 44463553533900/(1x905)
LCM = 44463553533900/905
LCM = 49130998380
Thus, we can understand that the LCM of 724,139,905,571,855 is 49130998380.
