Given numbers are 963,781,642,921,223
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 963,781,642,921,223 is 102979446966.
Find LCM of 963,781,642,921,223 with Prime Factorization
| 3 | 963, 781, 642, 921, 223 |
| 107 | 321, 781, 214, 307, 223 |
| 3, 781, 2, 307, 223 |
Multiply the prime numbers at the bottom and the left side.
3 x 107 x 3 x 781 x 2 x 307 x 223 = 102979446966
Therefore, the lowest common multiple of 963,781,642,921,223 is 102979446966.
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.
963 x 781 x 642 x 921 x 223 = 99169207428258
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.
963 : 1, 3, 9, 107, 321, 963
781 : 1, 11, 71, 781
642 : 1, 2, 3, 6, 107, 214, 321, 642
921 : 1, 3, 307, 921
223 : 1, 223
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 963,781,642,921,223, is 1.
Now, the common factors can be found like this.
963:3x 3x 107
781:11x 71
642:2x 3x 107
921:3x 307
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.
3x 3x 107 = 963
Therefore, the value for common factors is 963.
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 = 99169207428258/(1x963)
LCM = 99169207428258/963
LCM = 102979446966
Thus, we can understand that the LCM of 963,781,642,921,223 is 102979446966.
