Given numbers are 360,465,321,749
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 360,465,321,749 is 8358840.
Find LCM of 360,465,321,749 with Prime Factorization
| 3 | 360, 465, 321, 749 |
| 5 | 120, 155, 107, 749 |
| 107 | 24, 31, 107, 749 |
| 24, 31, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 107 x 24 x 31 x 1 x 7 = 8358840
Therefore, the lowest common multiple of 360,465,321,749 is 8358840.
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.
360 x 465 x 321 x 749 = 40247814600
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.
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
465 : 1, 3, 5, 15, 31, 93, 155, 465
321 : 1, 3, 107, 321
749 : 1, 7, 107, 749
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 360,465,321,749, is 1.
Now, the common factors can be found like this.
360:2x 2x 2x 3x 3x 5
465:3x 5x 31
321:3x 107
749:7x 107
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 5x 107 = 4815
Therefore, the value for common factors is 4815.
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 = 40247814600/(1x4815)
LCM = 40247814600/4815
LCM = 8358840
Thus, we can understand that the LCM of 360,465,321,749 is 8358840.
