Find LCM of 919,744,984,561,403 with Prime Factorization
| 2 | 919, 744, 984, 561, 403 |
| 2 | 919, 372, 492, 561, 403 |
| 2 | 919, 186, 246, 561, 403 |
| 3 | 919, 93, 123, 561, 403 |
| 31 | 919, 31, 41, 187, 403 |
| 919, 1, 41, 187, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 31 x 919 x 1 x 41 x 187 x 13 = 68148650856
Therefore, the lowest common multiple of 919,744,984,561,403 is 68148650856.
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.
919 x 744 x 984 x 561 x 403 = 152107788710592
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.
919 : 1, 919
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
561 : 1, 3, 11, 17, 33, 51, 187, 561
403 : 1, 13, 31, 403
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 919,744,984,561,403, is 1.
Now, the common factors can be found like this.
919:919
744:2x 2x 2x 3x 31
984:2x 2x 2x 3x 41
561:3x 11x 17
403:13x 31
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 3x 3x 31 = 2232
Therefore, the value for common factors is 2232.
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 = 152107788710592/(1x2232)
LCM = 152107788710592/2232
LCM = 68148650856
Thus, we can understand that the LCM of 919,744,984,561,403 is 68148650856.
