Given numbers are 700,840,787,666
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 700,840,787,666 is 366899400.
Find LCM of 700,840,787,666 with Prime Factorization
| 2 | 700, 840, 787, 666 |
| 2 | 350, 420, 787, 333 |
| 3 | 175, 210, 787, 333 |
| 5 | 175, 70, 787, 111 |
| 7 | 35, 14, 787, 111 |
| 5, 2, 787, 111 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 5 x 2 x 787 x 111 = 366899400
Therefore, the lowest common multiple of 700,840,787,666 is 366899400.
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.
700 x 840 x 787 x 666 = 308195496000
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.
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
787 : 1, 787
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 700,840,787,666, is 1.
Now, the common factors can be found like this.
700:2x 2x 5x 5x 7
840:2x 2x 2x 3x 5x 7
787:787
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 3x 5x 7 = 840
Therefore, the value for common factors is 840.
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 = 308195496000/(1x840)
LCM = 308195496000/840
LCM = 366899400
Thus, we can understand that the LCM of 700,840,787,666 is 366899400.
