The LCM of 411,257,780,380 is 521797380.
Find LCM of 411,257,780,380 with Prime Factorization
| 2 | 411, 257, 780, 380 |
| 2 | 411, 257, 390, 190 |
| 3 | 411, 257, 195, 95 |
| 5 | 137, 257, 65, 95 |
| 137, 257, 13, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 137 x 257 x 13 x 19 = 521797380
Therefore, the lowest common multiple of 411,257,780,380 is 521797380.
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.
411 x 257 x 780 x 380 = 31307842800
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.
411 : 1, 3, 137, 411
257 : 1, 257
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
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 411,257,780,380, is 1.
Now, the common factors can be found like this.
411:3x 137
257:257
780:2x 2x 3x 5x 13
380:2x 2x 5x 19
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 5 = 60
Therefore, the value for common factors is 60.
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 = 31307842800/(1x60)
LCM = 31307842800/60
LCM = 521797380
Thus, we can understand that the LCM of 411,257,780,380 is 521797380.
