Find LCM of 874,645,994,840,432 with Prime Factorization
2 | 874, 645, 994, 840, 432 |
2 | 437, 645, 497, 420, 216 |
2 | 437, 645, 497, 210, 108 |
3 | 437, 645, 497, 105, 54 |
5 | 437, 215, 497, 35, 18 |
7 | 437, 43, 497, 7, 18 |
437, 43, 71, 1, 18 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 7 x 437 x 43 x 71 x 1 x 18 = 20172514320
Therefore, the lowest common multiple of 874,645,994,840,432 is 20172514320.
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.
874 x 645 x 994 x 840 x 432 = 203338944345600
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.
874 : 1, 2, 19, 23, 38, 46, 437, 874
645 : 1, 3, 5, 15, 43, 129, 215, 645
994 : 1, 2, 7, 14, 71, 142, 497, 994
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 874,645,994,840,432, is 1.
Now, the common factors can be found like this.
874:2x 19x 23
645:3x 5x 43
994:2x 7x 71
840:2x 2x 2x 3x 5x 7
432:2x 2x 2x 2x 3x 3x 3
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 2x 3x 3x 5x 7 = 10080
Therefore, the value for common factors is 10080.
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 = 203338944345600/(1x10080)
LCM = 203338944345600/10080
LCM = 20172514320
Thus, we can understand that the LCM of 874,645,994,840,432 is 20172514320.
