Given numbers are 780,276,913,444,521
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 780,276,913,444,521 is 315742223940.
Find LCM of 780,276,913,444,521 with Prime Factorization
| 2 | 780, 276, 913, 444, 521 |
| 2 | 390, 138, 913, 222, 521 |
| 3 | 195, 69, 913, 111, 521 |
| 65, 23, 913, 37, 521 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 65 x 23 x 913 x 37 x 521 = 315742223940
Therefore, the lowest common multiple of 780,276,913,444,521 is 315742223940.
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 276 x 913 x 444 x 521 = 45466880247360
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
276 : 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276
913 : 1, 11, 83, 913
444 : 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444
521 : 1, 521
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,276,913,444,521, is 1.
Now, the common factors can be found like this.
780:2x 2x 3x 5x 13
276:2x 2x 3x 23
913:11x 83
444:2x 2x 3x 37
521:521
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 2x 2x 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 45466880247360/(1x144)
LCM = 45466880247360/144
LCM = 315742223940
Thus, we can understand that the LCM of 780,276,913,444,521 is 315742223940.
