Given numbers are 968,828,972,787
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 968,828,972,787 is 4257789624.
Find LCM of 968,828,972,787 with Prime Factorization
| 2 | 968, 828, 972, 787 |
| 2 | 484, 414, 486, 787 |
| 3 | 242, 207, 243, 787 |
| 3 | 242, 69, 81, 787 |
| 242, 23, 27, 787 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 242 x 23 x 27 x 787 = 4257789624
Therefore, the lowest common multiple of 968,828,972,787 is 4257789624.
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.
968 x 828 x 972 x 787 = 613121705856
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.
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
787 : 1, 787
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 968,828,972,787, is 1.
Now, the common factors can be found like this.
968:2x 2x 2x 11x 11
828:2x 2x 3x 3x 23
972:2x 2x 3x 3x 3x 3x 3
787:787
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 = 613121705856/(1x144)
LCM = 613121705856/144
LCM = 4257789624
Thus, we can understand that the LCM of 968,828,972,787 is 4257789624.
