Given numbers are 972,870,678,581,188
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 972,870,678,581,188 is 434897289540.
Find LCM of 972,870,678,581,188 with Prime Factorization
| 2 | 972, 870, 678, 581, 188 |
| 2 | 486, 435, 339, 581, 94 |
| 3 | 243, 435, 339, 581, 47 |
| 81, 145, 113, 581, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 81 x 145 x 113 x 581 x 47 = 434897289540
Therefore, the lowest common multiple of 972,870,678,581,188 is 434897289540.
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.
972 x 870 x 678 x 581 x 188 = 62625209693760
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.
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
678 : 1, 2, 3, 6, 113, 226, 339, 678
581 : 1, 7, 83, 581
188 : 1, 2, 4, 47, 94, 188
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,870,678,581,188, is 1.
Now, the common factors can be found like this.
972:2x 2x 3x 3x 3x 3x 3
870:2x 3x 5x 29
678:2x 3x 113
581:7x 83
188:2x 2x 47
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 2x 2x 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 62625209693760/(1x144)
LCM = 62625209693760/144
LCM = 434897289540
Thus, we can understand that the LCM of 972,870,678,581,188 is 434897289540.
