Given numbers are 778,893,868,952,454
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 778,893,868,952,454 is 2327156335448.
Find LCM of 778,893,868,952,454 with Prime Factorization
| 2 | 778, 893, 868, 952, 454 |
| 2 | 389, 893, 434, 476, 227 |
| 7 | 389, 893, 217, 238, 227 |
| 389, 893, 31, 34, 227 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 389 x 893 x 31 x 34 x 227 = 2327156335448
Therefore, the lowest common multiple of 778,893,868,952,454 is 2327156335448.
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 893 x 868 x 952 x 454 = 260641509570176
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
893 : 1, 19, 47, 893
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
952 : 1, 2, 4, 7, 8, 14, 17, 28, 34, 56, 68, 119, 136, 238, 476, 952
454 : 1, 2, 227, 454
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,893,868,952,454, is 1.
Now, the common factors can be found like this.
778:2x 389
893:19x 47
868:2x 2x 7x 31
952:2x 2x 2x 7x 17
454:2x 227
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 7 = 112
Therefore, the value for common factors is 112.
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 = 260641509570176/(1x112)
LCM = 260641509570176/112
LCM = 2327156335448
Thus, we can understand that the LCM of 778,893,868,952,454 is 2327156335448.
