Given numbers are 822,778,906,516,742
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 822,778,906,516,742 is 1540532010948.
Find LCM of 822,778,906,516,742 with Prime Factorization
| 2 | 822, 778, 906, 516, 742 |
| 3 | 411, 389, 453, 258, 371 |
| 137, 389, 151, 86, 371 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 137 x 389 x 151 x 86 x 371 = 1540532010948
Therefore, the lowest common multiple of 822,778,906,516,742 is 1540532010948.
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.
822 x 778 x 906 x 516 x 742 = 221836609576512
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.
822 : 1, 2, 3, 6, 137, 274, 411, 822
778 : 1, 2, 389, 778
906 : 1, 2, 3, 6, 151, 302, 453, 906
516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
742 : 1, 2, 7, 14, 53, 106, 371, 742
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 822,778,906,516,742, is 2.
Now, the common factors can be found like this.
822:2x 3x 137
778:2x 389
906:2x 3x 151
516:2x 2x 3x 43
742:2x 7x 53
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 3x 3 = 72
Therefore, the value for common factors is 72.
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 = 221836609576512/(2x72)
LCM = 221836609576512/144
LCM = 1540532010948
Thus, we can understand that the LCM of 822,778,906,516,742 is 1540532010948.
