Find LCM of 801,210,399,632,920 with Prime Factorization
| 2 | 801, 210, 399, 632, 920 |
| 2 | 801, 105, 399, 316, 460 |
| 2 | 801, 105, 399, 158, 230 |
| 3 | 801, 105, 399, 79, 115 |
| 5 | 267, 35, 133, 79, 115 |
| 7 | 267, 7, 133, 79, 23 |
| 267, 1, 19, 79, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 7 x 267 x 1 x 19 x 79 x 23 = 7742818440
Therefore, the lowest common multiple of 801,210,399,632,920 is 7742818440.
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 210 x 399 x 632 x 920 = 39023804937600
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
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
399 : 1, 3, 7, 19, 21, 57, 133, 399
632 : 1, 2, 4, 8, 79, 158, 316, 632
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 801,210,399,632,920, is 1.
Now, the common factors can be found like this.
801:3x 3x 89
210:2x 3x 5x 7
399:3x 7x 19
632:2x 2x 2x 79
920:2x 2x 2x 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.
2x 2x 2x 2x 3x 3x 5x 7 = 5040
Therefore, the value for common factors is 5040.
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 = 39023804937600/(1x5040)
LCM = 39023804937600/5040
LCM = 7742818440
Thus, we can understand that the LCM of 801,210,399,632,920 is 7742818440.
