Given numbers are 669,731,430,215,664
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 669,731,430,215,664 is 1623609480.
Find LCM of 669,731,430,215,664 with Prime Factorization
| 2 | 669, 731, 430, 215, 664 |
| 5 | 669, 731, 215, 215, 332 |
| 43 | 669, 731, 43, 43, 332 |
| 669, 17, 1, 1, 332 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 43 x 669 x 17 x 1 x 1 x 332 = 1623609480
Therefore, the lowest common multiple of 669,731,430,215,664 is 1623609480.
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 731 x 430 x 215 x 664 = 30020539285200
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
731 : 1, 17, 43, 731
430 : 1, 2, 5, 10, 43, 86, 215, 430
215 : 1, 5, 43, 215
664 : 1, 2, 4, 8, 83, 166, 332, 664
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,731,430,215,664, is 1.
Now, the common factors can be found like this.
669:3x 223
731:17x 43
430:2x 5x 43
215:5x 43
664:2x 2x 2x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 43x 43 = 18490
Therefore, the value for common factors is 18490.
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 = 30020539285200/(1x18490)
LCM = 30020539285200/18490
LCM = 1623609480
Thus, we can understand that the LCM of 669,731,430,215,664 is 1623609480.
