Given numbers are 979,858,671,972
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 979,858,671,972 is 754609284.
Find LCM of 979,858,671,972 with Prime Factorization
2 | 979, 858, 671, 972 |
3 | 979, 429, 671, 486 |
11 | 979, 143, 671, 162 |
89, 13, 61, 162 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 89 x 13 x 61 x 162 = 754609284
Therefore, the lowest common multiple of 979,858,671,972 is 754609284.
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.
979 x 858 x 671 x 972 = 547846340184
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.
979 : 1, 11, 89, 979
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
671 : 1, 11, 61, 671
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 979,858,671,972, is 1.
Now, the common factors can be found like this.
979:11x 89
858:2x 3x 11x 13
671:11x 61
972:2x 2x 3x 3x 3x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 11x 11 = 726
Therefore, the value for common factors is 726.
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 = 547846340184/(1x726)
LCM = 547846340184/726
LCM = 754609284
Thus, we can understand that the LCM of 979,858,671,972 is 754609284.
