The LCM of 767,615,410,780 is 1886820.
Find LCM of 767,615,410,780 with Prime Factorization
| 2 | 767, 615, 410, 780 |
| 3 | 767, 615, 205, 390 |
| 5 | 767, 205, 205, 130 |
| 13 | 767, 41, 41, 26 |
| 41 | 59, 41, 41, 2 |
| 59, 1, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 41 x 59 x 1 x 1 x 2 = 1886820
Therefore, the lowest common multiple of 767,615,410,780 is 1886820.
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.
767 x 615 x 410 x 780 = 150851259000
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.
767 : 1, 13, 59, 767
615 : 1, 3, 5, 15, 41, 123, 205, 615
410 : 1, 2, 5, 10, 41, 82, 205, 410
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 767,615,410,780, is 1.
Now, the common factors can be found like this.
767:13x 59
615:3x 5x 41
410:2x 5x 41
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 3x 5x 5x 13x 41 = 79950
Therefore, the value for common factors is 79950.
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 = 150851259000/(1x79950)
LCM = 150851259000/79950
LCM = 1886820
Thus, we can understand that the LCM of 767,615,410,780 is 1886820.
