Given numbers are 670,644,917,699,223
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 670,644,917,699,223 is 4405386421380.
Find LCM of 670,644,917,699,223 with Prime Factorization
| 2 | 670, 644, 917, 699, 223 |
| 7 | 335, 322, 917, 699, 223 |
| 335, 46, 131, 699, 223 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 335 x 46 x 131 x 699 x 223 = 4405386421380
Therefore, the lowest common multiple of 670,644,917,699,223 is 4405386421380.
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.
670 x 644 x 917 x 699 x 223 = 61675409899320
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.
670 : 1, 2, 5, 10, 67, 134, 335, 670
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
917 : 1, 7, 131, 917
699 : 1, 3, 233, 699
223 : 1, 223
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 670,644,917,699,223, is 1.
Now, the common factors can be found like this.
670:2x 5x 67
644:2x 2x 7x 23
917:7x 131
699:3x 233
223:223
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7 = 14
Therefore, the value for common factors is 14.
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 = 61675409899320/(1x14)
LCM = 61675409899320/14
LCM = 4405386421380
Thus, we can understand that the LCM of 670,644,917,699,223 is 4405386421380.
