Given numbers are 218,254,963,390,808
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 218,254,963,390,808 is 700134088680.
Find LCM of 218,254,963,390,808 with Prime Factorization
| 2 | 218, 254, 963, 390, 808 |
| 3 | 109, 127, 963, 195, 404 |
| 109, 127, 321, 65, 404 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 109 x 127 x 321 x 65 x 404 = 700134088680
Therefore, the lowest common multiple of 218,254,963,390,808 is 700134088680.
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.
218 x 254 x 963 x 390 x 808 = 16803218128320
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.
218 : 1, 2, 109, 218
254 : 1, 2, 127, 254
963 : 1, 3, 9, 107, 321, 963
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
808 : 1, 2, 4, 8, 101, 202, 404, 808
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 218,254,963,390,808, is 1.
Now, the common factors can be found like this.
218:2x 109
254:2x 127
963:3x 3x 107
390:2x 3x 5x 13
808:2x 2x 2x 101
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 3 = 24
Therefore, the value for common factors is 24.
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 = 16803218128320/(1x24)
LCM = 16803218128320/24
LCM = 700134088680
Thus, we can understand that the LCM of 218,254,963,390,808 is 700134088680.
