Given numbers are 105,621,897,699,456
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 105,621,897,699,456 is 10006967880.
Find LCM of 105,621,897,699,456 with Prime Factorization
| 3 | 105, 621, 897, 699, 456 |
| 23 | 35, 207, 299, 233, 152 |
| 35, 9, 13, 233, 152 |
Multiply the prime numbers at the bottom and the left side.
3 x 23 x 35 x 9 x 13 x 233 x 152 = 10006967880
Therefore, the lowest common multiple of 105,621,897,699,456 is 10006967880.
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.
105 x 621 x 897 x 699 x 456 = 18642981160440
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.
105 : 1, 3, 5, 7, 15, 21, 35, 105
621 : 1, 3, 9, 23, 27, 69, 207, 621
897 : 1, 3, 13, 23, 39, 69, 299, 897
699 : 1, 3, 233, 699
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 105,621,897,699,456, is 3.
Now, the common factors can be found like this.
105:3x 5x 7
621:3x 3x 3x 23
897:3x 13x 23
699:3x 233
456:2x 2x 2x 3x 19
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 3x 23 = 621
Therefore, the value for common factors is 621.
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 = 18642981160440/(3x621)
LCM = 18642981160440/1863
LCM = 10006967880
Thus, we can understand that the LCM of 105,621,897,699,456 is 10006967880.
