Given numbers are 645,767,363,579,240
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 645,767,363,579,240 is 184849270320.
Find LCM of 645,767,363,579,240 with Prime Factorization
| 3 | 645, 767, 363, 579, 240 |
| 5 | 215, 767, 121, 193, 80 |
| 43, 767, 121, 193, 16 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 43 x 767 x 121 x 193 x 16 = 184849270320
Therefore, the lowest common multiple of 645,767,363,579,240 is 184849270320.
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.
645 x 767 x 363 x 579 x 240 = 24954651493200
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.
645 : 1, 3, 5, 15, 43, 129, 215, 645
767 : 1, 13, 59, 767
363 : 1, 3, 11, 33, 121, 363
579 : 1, 3, 193, 579
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,767,363,579,240, is 1.
Now, the common factors can be found like this.
645:3x 5x 43
767:13x 59
363:3x 11x 11
579:3x 193
240:2x 2x 2x 2x 3x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 5 = 135
Therefore, the value for common factors is 135.
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 = 24954651493200/(1x135)
LCM = 24954651493200/135
LCM = 184849270320
Thus, we can understand that the LCM of 645,767,363,579,240 is 184849270320.
