Given numbers are 578,765,795,145
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 578,765,795,145 is 39977370.
Find LCM of 578,765,795,145 with Prime Factorization
| 3 | 578, 765, 795, 145 |
| 5 | 578, 255, 265, 145 |
| 17 | 578, 51, 53, 29 |
| 34, 3, 53, 29 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 17 x 34 x 3 x 53 x 29 = 39977370
Therefore, the lowest common multiple of 578,765,795,145 is 39977370.
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.
578 x 765 x 795 x 145 = 50971146750
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.
578 : 1, 2, 17, 34, 289, 578
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
795 : 1, 3, 5, 15, 53, 159, 265, 795
145 : 1, 5, 29, 145
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,765,795,145, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
765:3x 3x 5x 17
795:3x 5x 53
145:5x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 17 = 1275
Therefore, the value for common factors is 1275.
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 = 50971146750/(1x1275)
LCM = 50971146750/1275
LCM = 39977370
Thus, we can understand that the LCM of 578,765,795,145 is 39977370.
