Find LCM of 814,418,651,931 with Prime Factorization
| 2 | 814, 418, 651, 931 |
| 7 | 407, 209, 651, 931 |
| 11 | 407, 209, 93, 133 |
| 19 | 37, 19, 93, 133 |
| 37, 1, 93, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 19 x 37 x 1 x 93 x 7 = 70478562
Therefore, the lowest common multiple of 814,418,651,931 is 70478562.
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.
814 x 418 x 651 x 931 = 206220272412
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.
814 : 1, 2, 11, 22, 37, 74, 407, 814
418 : 1, 2, 11, 19, 22, 38, 209, 418
651 : 1, 3, 7, 21, 31, 93, 217, 651
931 : 1, 7, 19, 49, 133, 931
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 814,418,651,931, is 1.
Now, the common factors can be found like this.
814:2x 11x 37
418:2x 11x 19
651:3x 7x 31
931:7x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 11x 19 = 2926
Therefore, the value for common factors is 2926.
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 = 206220272412/(1x2926)
LCM = 206220272412/2926
LCM = 70478562
Thus, we can understand that the LCM of 814,418,651,931 is 70478562.
