Given numbers are 220,544,988,969
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 220,544,988,969 is 22170720.
Find LCM of 220,544,988,969 with Prime Factorization
| 2 | 220, 544, 988, 969 |
| 2 | 110, 272, 494, 969 |
| 17 | 55, 136, 247, 969 |
| 19 | 55, 8, 247, 57 |
| 55, 8, 13, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 19 x 55 x 8 x 13 x 3 = 22170720
Therefore, the lowest common multiple of 220,544,988,969 is 22170720.
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.
220 x 544 x 988 x 969 = 114578280960
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.
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544
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 220,544,988,969, is 1.
Now, the common factors can be found like this.
220:2x 2x 5x 11
544:2x 2x 2x 2x 2x 17
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 2x 2x 2x 17x 19 = 5168
Therefore, the value for common factors is 5168.
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 = 114578280960/(1x5168)
LCM = 114578280960/5168
LCM = 22170720
Thus, we can understand that the LCM of 220,544,988,969 is 22170720.
