Find LCM of 778,153,861,873,581 with Prime Factorization
| 3 | 778, 153, 861, 873, 581 |
| 3 | 778, 51, 287, 291, 581 |
| 7 | 778, 17, 287, 97, 581 |
| 778, 17, 41, 97, 83 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 778 x 17 x 41 x 97 x 83 = 275044364658
Therefore, the lowest common multiple of 778,153,861,873,581 is 275044364658.
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.
778 x 153 x 861 x 873 x 581 = 51983384920362
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.
778 : 1, 2, 389, 778
153 : 1, 3, 9, 17, 51, 153
861 : 1, 3, 7, 21, 41, 123, 287, 861
873 : 1, 3, 9, 97, 291, 873
581 : 1, 7, 83, 581
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,153,861,873,581, is 1.
Now, the common factors can be found like this.
778:2x 389
153:3x 3x 17
861:3x 7x 41
873:3x 3x 97
581:7x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 7 = 189
Therefore, the value for common factors is 189.
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 = 51983384920362/(1x189)
LCM = 51983384920362/189
LCM = 275044364658
Thus, we can understand that the LCM of 778,153,861,873,581 is 275044364658.
