The LCM of 793,766,309,618,821 is 154100338782.
Find LCM of 793,766,309,618,821 with Prime Factorization
| 2 | 793, 766, 309, 618, 821 |
| 3 | 793, 383, 309, 309, 821 |
| 103 | 793, 383, 103, 103, 821 |
| 793, 383, 1, 1, 821 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 103 x 793 x 383 x 1 x 1 x 821 = 154100338782
Therefore, the lowest common multiple of 793,766,309,618,821 is 154100338782.
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.
793 x 766 x 309 x 618 x 821 = 95234009367276
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.
793 : 1, 13, 61, 793
766 : 1, 2, 383, 766
309 : 1, 3, 103, 309
618 : 1, 2, 3, 6, 103, 206, 309, 618
821 : 1, 821
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 793,766,309,618,821, is 1.
Now, the common factors can be found like this.
793:13x 61
766:2x 383
309:3x 103
618:2x 3x 103
821:821
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 103 = 618
Therefore, the value for common factors is 618.
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 = 95234009367276/(1x618)
LCM = 95234009367276/618
LCM = 154100338782
Thus, we can understand that the LCM of 793,766,309,618,821 is 154100338782.
