Given numbers are 210,869,630,822
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 210,869,630,822 is 75003390.
Find LCM of 210,869,630,822 with Prime Factorization
| 2 | 210, 869, 630, 822 |
| 3 | 105, 869, 315, 411 |
| 5 | 35, 869, 105, 137 |
| 7 | 7, 869, 21, 137 |
| 1, 869, 3, 137 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 1 x 869 x 3 x 137 = 75003390
Therefore, the lowest common multiple of 210,869,630,822 is 75003390.
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.
210 x 869 x 630 x 822 = 94504271400
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.
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
869 : 1, 11, 79, 869
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
822 : 1, 2, 3, 6, 137, 274, 411, 822
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 210,869,630,822, is 1.
Now, the common factors can be found like this.
210:2x 3x 5x 7
869:11x 79
630:2x 3x 3x 5x 7
822:2x 3x 137
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 3x 3x 5x 7 = 1260
Therefore, the value for common factors is 1260.
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 = 94504271400/(1x1260)
LCM = 94504271400/1260
LCM = 75003390
Thus, we can understand that the LCM of 210,869,630,822 is 75003390.
