Find LCM of 905,464,145,782,756 with Prime Factorization
| 2 | 905, 464, 145, 782, 756 |
| 2 | 905, 232, 145, 391, 378 |
| 5 | 905, 116, 145, 391, 189 |
| 29 | 181, 116, 29, 391, 189 |
| 181, 4, 1, 391, 189 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 29 x 181 x 4 x 1 x 391 x 189 = 31031668080
Therefore, the lowest common multiple of 905,464,145,782,756 is 31031668080.
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.
905 x 464 x 145 x 782 x 756 = 35996734972800
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.
905 : 1, 5, 181, 905
464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464
145 : 1, 5, 29, 145
782 : 1, 2, 17, 23, 34, 46, 391, 782
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 905,464,145,782,756, is 1.
Now, the common factors can be found like this.
905:5x 181
464:2x 2x 2x 2x 29
145:5x 29
782:2x 17x 23
756:2x 2x 3x 3x 3x 7
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 29 = 1160
Therefore, the value for common factors is 1160.
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 = 35996734972800/(1x1160)
LCM = 35996734972800/1160
LCM = 31031668080
Thus, we can understand that the LCM of 905,464,145,782,756 is 31031668080.
