The LCM of 778,352,663,440 is 453916320.
Find LCM of 778,352,663,440 with Prime Factorization
| 2 | 778, 352, 663, 440 |
| 2 | 389, 176, 663, 220 |
| 2 | 389, 88, 663, 110 |
| 11 | 389, 44, 663, 55 |
| 389, 4, 663, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 11 x 389 x 4 x 663 x 5 = 453916320
Therefore, the lowest common multiple of 778,352,663,440 is 453916320.
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 352 x 663 x 440 = 79889272320
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
352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352
663 : 1, 3, 13, 17, 39, 51, 221, 663
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,352,663,440, is 1.
Now, the common factors can be found like this.
778:2x 389
352:2x 2x 2x 2x 2x 11
663:3x 13x 17
440:2x 2x 2x 5x 11
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 2x 11 = 176
Therefore, the value for common factors is 176.
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 = 79889272320/(1x176)
LCM = 79889272320/176
LCM = 453916320
Thus, we can understand that the LCM of 778,352,663,440 is 453916320.
