Find LCM of 801,942,556,572,451 with Prime Factorization
| 2 | 801, 942, 556, 572, 451 |
| 2 | 801, 471, 278, 286, 451 |
| 3 | 801, 471, 139, 143, 451 |
| 11 | 267, 157, 139, 143, 451 |
| 267, 157, 139, 13, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 267 x 157 x 139 x 13 x 41 = 409946189796
Therefore, the lowest common multiple of 801,942,556,572,451 is 409946189796.
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.
801 x 942 x 556 x 572 x 451 = 108225794106144
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.
801 : 1, 3, 9, 89, 267, 801
942 : 1, 2, 3, 6, 157, 314, 471, 942
556 : 1, 2, 4, 139, 278, 556
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
451 : 1, 11, 41, 451
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 801,942,556,572,451, is 1.
Now, the common factors can be found like this.
801:3x 3x 89
942:2x 3x 157
556:2x 2x 139
572:2x 2x 11x 13
451:11x 41
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 11 = 264
Therefore, the value for common factors is 264.
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 = 108225794106144/(1x264)
LCM = 108225794106144/264
LCM = 409946189796
Thus, we can understand that the LCM of 801,942,556,572,451 is 409946189796.
