Given numbers are 470,742,583,866,790
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 470,742,583,866,790 is 65611420490.
Find LCM of 470,742,583,866,790 with Prime Factorization
| 2 | 470, 742, 583, 866, 790 |
| 5 | 235, 371, 583, 433, 395 |
| 53 | 47, 371, 583, 433, 79 |
| 47, 7, 11, 433, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 53 x 47 x 7 x 11 x 433 x 79 = 65611420490
Therefore, the lowest common multiple of 470,742,583,866,790 is 65611420490.
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.
470 x 742 x 583 x 866 x 790 = 139096211438800
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.
470 : 1, 2, 5, 10, 47, 94, 235, 470
742 : 1, 2, 7, 14, 53, 106, 371, 742
583 : 1, 11, 53, 583
866 : 1, 2, 433, 866
790 : 1, 2, 5, 10, 79, 158, 395, 790
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 470,742,583,866,790, is 1.
Now, the common factors can be found like this.
470:2x 5x 47
742:2x 7x 53
583:11x 53
866:2x 433
790:2x 5x 79
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 53 = 2120
Therefore, the value for common factors is 2120.
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 = 139096211438800/(1x2120)
LCM = 139096211438800/2120
LCM = 65611420490
Thus, we can understand that the LCM of 470,742,583,866,790 is 65611420490.
