Find LCM of 630,549,222,343,855 with Prime Factorization
| 2 | 630, 549, 222, 343, 855 |
| 3 | 315, 549, 111, 343, 855 |
| 3 | 105, 183, 37, 343, 285 |
| 5 | 35, 61, 37, 343, 95 |
| 7 | 7, 61, 37, 343, 19 |
| 1, 61, 37, 49, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 7 x 1 x 61 x 37 x 49 x 19 = 1323798210
Therefore, the lowest common multiple of 630,549,222,343,855 is 1323798210.
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 549 x 222 x 343 x 855 = 22517807552100
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
549 : 1, 3, 9, 61, 183, 549
222 : 1, 2, 3, 6, 37, 74, 111, 222
343 : 1, 7, 49, 343
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,549,222,343,855, is 1.
Now, the common factors can be found like this.
630:2x 3x 3x 5x 7
549:3x 3x 61
222:2x 3x 37
343:7x 7x 7
855:3x 3x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3x 3x 5x 7 = 17010
Therefore, the value for common factors is 17010.
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 = 22517807552100/(1x17010)
LCM = 22517807552100/17010
LCM = 1323798210
Thus, we can understand that the LCM of 630,549,222,343,855 is 1323798210.
