Find LCM of 654,107,380,418,321 with Prime Factorization
2 | 654, 107, 380, 418, 321 |
3 | 327, 107, 190, 209, 321 |
19 | 109, 107, 190, 209, 107 |
107 | 109, 107, 10, 11, 107 |
109, 1, 10, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 107 x 109 x 1 x 10 x 11 x 1 = 146254020
Therefore, the lowest common multiple of 654,107,380,418,321 is 146254020.
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.
654 x 107 x 380 x 418 x 321 = 3568013071920
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.
654 : 1, 2, 3, 6, 109, 218, 327, 654
107 : 1, 107
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
418 : 1, 2, 11, 19, 22, 38, 209, 418
321 : 1, 3, 107, 321
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 654,107,380,418,321, is 1.
Now, the common factors can be found like this.
654:2x 3x 109
107:107
380:2x 2x 5x 19
418:2x 11x 19
321:3x 107
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 3x 19x 107 = 24396
Therefore, the value for common factors is 24396.
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 = 3568013071920/(1x24396)
LCM = 3568013071920/24396
LCM = 146254020
Thus, we can understand that the LCM of 654,107,380,418,321 is 146254020.
