Given numbers are 641,693,980,322,308
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 641,693,980,322,308 is 1430365860.
Find LCM of 641,693,980,322,308 with Prime Factorization
| 2 | 641, 693, 980, 322, 308 |
| 2 | 641, 693, 490, 161, 154 |
| 7 | 641, 693, 245, 161, 77 |
| 11 | 641, 99, 35, 23, 11 |
| 641, 9, 35, 23, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 11 x 641 x 9 x 35 x 23 x 1 = 1430365860
Therefore, the lowest common multiple of 641,693,980,322,308 is 1430365860.
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.
641 x 693 x 980 x 322 x 308 = 43174163118240
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.
641 : 1, 641
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
322 : 1, 2, 7, 14, 23, 46, 161, 322
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,693,980,322,308, is 1.
Now, the common factors can be found like this.
641:641
693:3x 3x 7x 11
980:2x 2x 5x 7x 7
322:2x 7x 23
308:2x 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 7x 7x 7x 11 = 30184
Therefore, the value for common factors is 30184.
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 = 43174163118240/(1x30184)
LCM = 43174163118240/30184
LCM = 1430365860
Thus, we can understand that the LCM of 641,693,980,322,308 is 1430365860.
