Find LCM of 630,581,218,810 with Prime Factorization
2 | 630, 581, 218, 810 |
3 | 315, 581, 109, 405 |
3 | 105, 581, 109, 135 |
5 | 35, 581, 109, 45 |
7 | 7, 581, 109, 9 |
1, 83, 109, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 7 x 1 x 83 x 109 x 9 = 51296490
Therefore, the lowest common multiple of 630,581,218,810 is 51296490.
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.
630 x 581 x 218 x 810 = 64633577400
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.
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
581 : 1, 7, 83, 581
218 : 1, 2, 109, 218
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,581,218,810, is 1.
Now, the common factors can be found like this.
630:2x 3x 3x 5x 7
581:7x 83
218:2x 109
810:2x 3x 3x 3x 3x 5
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 = 64633577400/(1x1260)
LCM = 64633577400/1260
LCM = 51296490
Thus, we can understand that the LCM of 630,581,218,810 is 51296490.
