The LCM of 422,801,780,175,868 is 47678003100.
Find LCM of 422,801,780,175,868 with Prime Factorization
| 2 | 422, 801, 780, 175, 868 |
| 2 | 211, 801, 390, 175, 434 |
| 3 | 211, 801, 195, 175, 217 |
| 5 | 211, 267, 65, 175, 217 |
| 7 | 211, 267, 13, 35, 217 |
| 211, 267, 13, 5, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 211 x 267 x 13 x 5 x 31 = 47678003100
Therefore, the lowest common multiple of 422,801,780,175,868 is 47678003100.
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.
422 x 801 x 780 x 175 x 868 = 40049522604000
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.
422 : 1, 2, 211, 422
801 : 1, 3, 9, 89, 267, 801
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
175 : 1, 5, 7, 25, 35, 175
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,801,780,175,868, is 1.
Now, the common factors can be found like this.
422:2x 211
801:3x 3x 89
780:2x 2x 3x 5x 13
175:5x 5x 7
868:2x 2x 7x 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 5x 7 = 840
Therefore, the value for common factors is 840.
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 = 40049522604000/(1x840)
LCM = 40049522604000/840
LCM = 47678003100
Thus, we can understand that the LCM of 422,801,780,175,868 is 47678003100.
