Given numbers are 780,451,130,341
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 780,451,130,341 is 10905180.
Find LCM of 780,451,130,341 with Prime Factorization
| 2 | 780, 451, 130, 341 |
| 5 | 390, 451, 65, 341 |
| 11 | 78, 451, 13, 341 |
| 13 | 78, 41, 13, 31 |
| 6, 41, 1, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 13 x 6 x 41 x 1 x 31 = 10905180
Therefore, the lowest common multiple of 780,451,130,341 is 10905180.
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.
780 x 451 x 130 x 341 = 15594407400
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.
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
451 : 1, 11, 41, 451
130 : 1, 2, 5, 10, 13, 26, 65, 130
341 : 1, 11, 31, 341
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,451,130,341, is 1.
Now, the common factors can be found like this.
780:2x 2x 3x 5x 13
451:11x 41
130:2x 5x 13
341:11x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 11x 13 = 1430
Therefore, the value for common factors is 1430.
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 = 15594407400/(1x1430)
LCM = 15594407400/1430
LCM = 10905180
Thus, we can understand that the LCM of 780,451,130,341 is 10905180.
