Given numbers are 755,280,605,301,389
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 755,280,605,301,389 is 85573324760.
Find LCM of 755,280,605,301,389 with Prime Factorization
| 5 | 755, 280, 605, 301, 389 |
| 7 | 151, 56, 121, 301, 389 |
| 151, 8, 121, 43, 389 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 151 x 8 x 121 x 43 x 389 = 85573324760
Therefore, the lowest common multiple of 755,280,605,301,389 is 85573324760.
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.
755 x 280 x 605 x 301 x 389 = 14975331833000
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.
755 : 1, 5, 151, 755
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
605 : 1, 5, 11, 55, 121, 605
301 : 1, 7, 43, 301
389 : 1, 389
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 755,280,605,301,389, is 1.
Now, the common factors can be found like this.
755:5x 151
280:2x 2x 2x 5x 7
605:5x 11x 11
301:7x 43
389:389
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 7 = 175
Therefore, the value for common factors is 175.
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 = 14975331833000/(1x175)
LCM = 14975331833000/175
LCM = 85573324760
Thus, we can understand that the LCM of 755,280,605,301,389 is 85573324760.
