The LCM of 778,989,863,465,345 is 308773227390.
Find LCM of 778,989,863,465,345 with Prime Factorization
| 3 | 778, 989, 863, 465, 345 |
| 5 | 778, 989, 863, 155, 115 |
| 23 | 778, 989, 863, 31, 23 |
| 778, 43, 863, 31, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 23 x 778 x 43 x 863 x 31 x 1 = 308773227390
Therefore, the lowest common multiple of 778,989,863,465,345 is 308773227390.
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 989 x 863 x 465 x 345 = 106526763449550
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
989 : 1, 23, 43, 989
863 : 1, 863
465 : 1, 3, 5, 15, 31, 93, 155, 465
345 : 1, 3, 5, 15, 23, 69, 115, 345
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,989,863,465,345, is 1.
Now, the common factors can be found like this.
778:2x 389
989:23x 43
863:863
465:3x 5x 31
345:3x 5x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 23 = 345
Therefore, the value for common factors is 345.
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 = 106526763449550/(1x345)
LCM = 106526763449550/345
LCM = 308773227390
Thus, we can understand that the LCM of 778,989,863,465,345 is 308773227390.
