Given numbers are 747,765,408,579
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 747,765,408,579 is 98036280.
Find LCM of 747,765,408,579 with Prime Factorization
3 | 747, 765, 408, 579 |
3 | 249, 255, 136, 193 |
17 | 83, 85, 136, 193 |
83, 5, 8, 193 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 17 x 83 x 5 x 8 x 193 = 98036280
Therefore, the lowest common multiple of 747,765,408,579 is 98036280.
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.
747 x 765 x 408 x 579 = 134995957560
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.
747 : 1, 3, 9, 83, 249, 747
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
579 : 1, 3, 193, 579
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 747,765,408,579, is 3.
Now, the common factors can be found like this.
747:3x 3x 83
765:3x 3x 5x 17
408:2x 2x 2x 3x 17
579:3x 193
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 17 = 459
Therefore, the value for common factors is 459.
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 = 134995957560/(3x459)
LCM = 134995957560/1377
LCM = 98036280
Thus, we can understand that the LCM of 747,765,408,579 is 98036280.
