Find LCM of 657,207,856,279,990 with Prime Factorization
2 | 657, 207, 856, 279, 990 |
3 | 657, 207, 428, 279, 495 |
3 | 219, 69, 428, 93, 165 |
73, 23, 428, 31, 55 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 73 x 23 x 428 x 31 x 55 = 22054202280
Therefore, the lowest common multiple of 657,207,856,279,990 is 22054202280.
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.
657 x 207 x 856 x 279 x 990 = 32155026924240
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.
657 : 1, 3, 9, 73, 219, 657
207 : 1, 3, 9, 23, 69, 207
856 : 1, 2, 4, 8, 107, 214, 428, 856
279 : 1, 3, 9, 31, 93, 279
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,207,856,279,990, is 1.
Now, the common factors can be found like this.
657:3x 3x 73
207:3x 3x 23
856:2x 2x 2x 107
279:3x 3x 31
990:2x 3x 3x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3x 3x 3 = 1458
Therefore, the value for common factors is 1458.
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 = 32155026924240/(1x1458)
LCM = 32155026924240/1458
LCM = 22054202280
Thus, we can understand that the LCM of 657,207,856,279,990 is 22054202280.
