Given numbers are 220,214,940,154
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 220,214,940,154 is 7744660.
Find LCM of 220,214,940,154 with Prime Factorization
| 2 | 220, 214, 940, 154 |
| 2 | 110, 107, 470, 77 |
| 5 | 55, 107, 235, 77 |
| 11 | 11, 107, 47, 77 |
| 1, 107, 47, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 1 x 107 x 47 x 7 = 7744660
Therefore, the lowest common multiple of 220,214,940,154 is 7744660.
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 214 x 940 x 154 = 6815300800
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
214 : 1, 2, 107, 214
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
154 : 1, 2, 7, 11, 14, 22, 77, 154
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,214,940,154, is 2.
Now, the common factors can be found like this.
220:2x 2x 5x 11
214:2x 107
940:2x 2x 5x 47
154:2x 7x 11
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 5x 11 = 440
Therefore, the value for common factors is 440.
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 = 6815300800/(2x440)
LCM = 6815300800/880
LCM = 7744660
Thus, we can understand that the LCM of 220,214,940,154 is 7744660.
