Given numbers are 780,393,562,904,666
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 780,393,562,904,666 is 720283781880.
Find LCM of 780,393,562,904,666 with Prime Factorization
| 2 | 780, 393, 562, 904, 666 |
| 2 | 390, 393, 281, 452, 333 |
| 3 | 195, 393, 281, 226, 333 |
| 65, 131, 281, 226, 111 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 65 x 131 x 281 x 226 x 111 = 720283781880
Therefore, the lowest common multiple of 780,393,562,904,666 is 720283781880.
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 393 x 562 x 904 x 666 = 103720864590720
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
393 : 1, 3, 131, 393
562 : 1, 2, 281, 562
904 : 1, 2, 4, 8, 113, 226, 452, 904
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,393,562,904,666, is 1.
Now, the common factors can be found like this.
780:2x 2x 3x 5x 13
393:3x 131
562:2x 281
904:2x 2x 2x 113
666:2x 3x 3x 37
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 = 103720864590720/(1x144)
LCM = 103720864590720/144
LCM = 720283781880
Thus, we can understand that the LCM of 780,393,562,904,666 is 720283781880.
