Given numbers are 669,406,368,989,276
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 669,406,368,989,276 is 2149009968.
Find LCM of 669,406,368,989,276 with Prime Factorization
| 2 | 669, 406, 368, 989, 276 |
| 2 | 669, 203, 184, 989, 138 |
| 3 | 669, 203, 92, 989, 69 |
| 23 | 223, 203, 92, 989, 23 |
| 223, 203, 4, 43, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 23 x 223 x 203 x 4 x 43 x 1 = 2149009968
Therefore, the lowest common multiple of 669,406,368,989,276 is 2149009968.
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.
669 x 406 x 368 x 989 x 276 = 27283830553728
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.
669 : 1, 3, 223, 669
406 : 1, 2, 7, 14, 29, 58, 203, 406
368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368
989 : 1, 23, 43, 989
276 : 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,406,368,989,276, is 1.
Now, the common factors can be found like this.
669:3x 223
406:2x 7x 29
368:2x 2x 2x 2x 23
989:23x 43
276:2x 2x 3x 23
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 3x 23x 23 = 12696
Therefore, the value for common factors is 12696.
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 = 27283830553728/(1x12696)
LCM = 27283830553728/12696
LCM = 2149009968
Thus, we can understand that the LCM of 669,406,368,989,276 is 2149009968.
