Given numbers are 354,780,806,863,869
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 354,780,806,863,869 is 1069889389140.
Find LCM of 354,780,806,863,869 with Prime Factorization
| 2 | 354, 780, 806, 863, 869 |
| 3 | 177, 390, 403, 863, 869 |
| 13 | 59, 130, 403, 863, 869 |
| 59, 10, 31, 863, 869 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 59 x 10 x 31 x 863 x 869 = 1069889389140
Therefore, the lowest common multiple of 354,780,806,863,869 is 1069889389140.
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.
354 x 780 x 806 x 863 x 869 = 166902744705840
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.
354 : 1, 2, 3, 6, 59, 118, 177, 354
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
806 : 1, 2, 13, 26, 31, 62, 403, 806
863 : 1, 863
869 : 1, 11, 79, 869
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 354,780,806,863,869, is 1.
Now, the common factors can be found like this.
354:2x 3x 59
780:2x 2x 3x 5x 13
806:2x 13x 31
863:863
869:11x 79
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 3x 13 = 156
Therefore, the value for common factors is 156.
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 = 166902744705840/(1x156)
LCM = 166902744705840/156
LCM = 1069889389140
Thus, we can understand that the LCM of 354,780,806,863,869 is 1069889389140.
