Given numbers are 973,682,840,155
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 973,682,840,155 is 39815160.
Find LCM of 973,682,840,155 with Prime Factorization
| 2 | 973, 682, 840, 155 |
| 5 | 973, 341, 420, 155 |
| 7 | 973, 341, 84, 31 |
| 31 | 139, 341, 12, 31 |
| 139, 11, 12, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 31 x 139 x 11 x 12 x 1 = 39815160
Therefore, the lowest common multiple of 973,682,840,155 is 39815160.
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.
973 x 682 x 840 x 155 = 86398897200
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.
973 : 1, 7, 139, 973
682 : 1, 2, 11, 22, 31, 62, 341, 682
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
155 : 1, 5, 31, 155
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 973,682,840,155, is 1.
Now, the common factors can be found like this.
973:7x 139
682:2x 11x 31
840:2x 2x 2x 3x 5x 7
155:5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7x 31 = 2170
Therefore, the value for common factors is 2170.
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 = 86398897200/(1x2170)
LCM = 86398897200/2170
LCM = 39815160
Thus, we can understand that the LCM of 973,682,840,155 is 39815160.
