Find LCM of 381,532,285,780 with Prime Factorization
2 | 381, 532, 285, 780 |
2 | 381, 266, 285, 390 |
3 | 381, 133, 285, 195 |
5 | 127, 133, 95, 65 |
19 | 127, 133, 19, 13 |
127, 7, 1, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 19 x 127 x 7 x 1 x 13 = 13174980
Therefore, the lowest common multiple of 381,532,285,780 is 13174980.
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.
381 x 532 x 285 x 780 = 45058431600
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.
381 : 1, 3, 127, 381
532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532
285 : 1, 3, 5, 15, 19, 57, 95, 285
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,532,285,780, is 1.
Now, the common factors can be found like this.
381:3x 127
532:2x 2x 7x 19
285:3x 5x 19
780:2x 2x 3x 5x 13
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 3x 5x 19 = 3420
Therefore, the value for common factors is 3420.
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 = 45058431600/(1x3420)
LCM = 45058431600/3420
LCM = 13174980
Thus, we can understand that the LCM of 381,532,285,780 is 13174980.
