Given numbers are 899,784,946,689,105
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 899,784,946,689,105 is 3445461299280.
Find LCM of 899,784,946,689,105 with Prime Factorization
| 2 | 899, 784, 946, 689, 105 |
| 7 | 899, 392, 473, 689, 105 |
| 899, 56, 473, 689, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 899 x 56 x 473 x 689 x 15 = 3445461299280
Therefore, the lowest common multiple of 899,784,946,689,105 is 3445461299280.
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.
899 x 784 x 946 x 689 x 105 = 48236458189920
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.
899 : 1, 29, 31, 899
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
946 : 1, 2, 11, 22, 43, 86, 473, 946
689 : 1, 13, 53, 689
105 : 1, 3, 5, 7, 15, 21, 35, 105
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 899,784,946,689,105, is 1.
Now, the common factors can be found like this.
899:29x 31
784:2x 2x 2x 2x 7x 7
946:2x 11x 43
689:13x 53
105:3x 5x 7
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 = 48236458189920/(1x14)
LCM = 48236458189920/14
LCM = 3445461299280
Thus, we can understand that the LCM of 899,784,946,689,105 is 3445461299280.
