Given numbers are 700,412,802,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 700,412,802,840 is 173472600.
Find LCM of 700,412,802,840 with Prime Factorization
| 2 | 700, 412, 802, 840 |
| 2 | 350, 206, 401, 420 |
| 5 | 175, 103, 401, 210 |
| 7 | 35, 103, 401, 42 |
| 5, 103, 401, 6 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 5 x 103 x 401 x 6 = 173472600
Therefore, the lowest common multiple of 700,412,802,840 is 173472600.
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 412 x 802 x 840 = 194289312000
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
412 : 1, 2, 4, 103, 206, 412
802 : 1, 2, 401, 802
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
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 700,412,802,840, is 2.
Now, the common factors can be found like this.
700:2x 2x 5x 5x 7
412:2x 2x 103
802:2x 401
840:2x 2x 2x 3x 5x 7
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 5x 7 = 560
Therefore, the value for common factors is 560.
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 = 194289312000/(2x560)
LCM = 194289312000/1120
LCM = 173472600
Thus, we can understand that the LCM of 700,412,802,840 is 173472600.
