Find LCM of 273,438,631,988,969 with Prime Factorization
| 2 | 273, 438, 631, 988, 969 |
| 3 | 273, 219, 631, 494, 969 |
| 13 | 91, 73, 631, 494, 323 |
| 19 | 7, 73, 631, 38, 323 |
| 7, 73, 631, 2, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 19 x 7 x 73 x 631 x 2 x 17 = 16247157108
Therefore, the lowest common multiple of 273,438,631,988,969 is 16247157108.
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.
273 x 438 x 631 x 988 x 969 = 72234860502168
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.
273 : 1, 3, 7, 13, 21, 39, 91, 273
438 : 1, 2, 3, 6, 73, 146, 219, 438
631 : 1, 631
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
969 : 1, 3, 17, 19, 51, 57, 323, 969
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 273,438,631,988,969, is 1.
Now, the common factors can be found like this.
273:3x 7x 13
438:2x 3x 73
631:631
988:2x 2x 13x 19
969:3x 17x 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 13x 19 = 4446
Therefore, the value for common factors is 4446.
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 = 72234860502168/(1x4446)
LCM = 72234860502168/4446
LCM = 16247157108
Thus, we can understand that the LCM of 273,438,631,988,969 is 16247157108.
