Given numbers are 854,691,980,435,898
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 854,691,980,435,898 is 1613613622740.
Find LCM of 854,691,980,435,898 with Prime Factorization
| 2 | 854, 691, 980, 435, 898 |
| 5 | 427, 691, 490, 435, 449 |
| 7 | 427, 691, 98, 87, 449 |
| 61, 691, 14, 87, 449 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 61 x 691 x 14 x 87 x 449 = 1613613622740
Therefore, the lowest common multiple of 854,691,980,435,898 is 1613613622740.
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.
854 x 691 x 980 x 435 x 898 = 225905907183600
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.
854 : 1, 2, 7, 14, 61, 122, 427, 854
691 : 1, 691
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
435 : 1, 3, 5, 15, 29, 87, 145, 435
898 : 1, 2, 449, 898
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 854,691,980,435,898, is 1.
Now, the common factors can be found like this.
854:2x 7x 61
691:691
980:2x 2x 5x 7x 7
435:3x 5x 29
898:2x 449
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 5x 7 = 140
Therefore, the value for common factors is 140.
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 = 225905907183600/(1x140)
LCM = 225905907183600/140
LCM = 1613613622740
Thus, we can understand that the LCM of 854,691,980,435,898 is 1613613622740.
