Given numbers are 470,826,658,791
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 470,826,658,791 is 21934430.
Find LCM of 470,826,658,791 with Prime Factorization
| 2 | 470, 826, 658, 791 |
| 7 | 235, 413, 329, 791 |
| 47 | 235, 59, 47, 113 |
| 5, 59, 1, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 47 x 5 x 59 x 1 x 113 = 21934430
Therefore, the lowest common multiple of 470,826,658,791 is 21934430.
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 826 x 658 x 791 = 202059969160
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
826 : 1, 2, 7, 14, 59, 118, 413, 826
658 : 1, 2, 7, 14, 47, 94, 329, 658
791 : 1, 7, 113, 791
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 470,826,658,791, is 1.
Now, the common factors can be found like this.
470:2x 5x 47
826:2x 7x 59
658:2x 7x 47
791:7x 113
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 7x 7x 47 = 9212
Therefore, the value for common factors is 9212.
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 = 202059969160/(1x9212)
LCM = 202059969160/9212
LCM = 21934430
Thus, we can understand that the LCM of 470,826,658,791 is 21934430.
