Given numbers are 321,732,915,473
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 321,732,915,473 is 185236260.
Find LCM of 321,732,915,473 with Prime Factorization
| 3 | 321, 732, 915, 473 |
| 61 | 107, 244, 305, 473 |
| 107, 4, 5, 473 |
Multiply the prime numbers at the bottom and the left side.
3 x 61 x 107 x 4 x 5 x 473 = 185236260
Therefore, the lowest common multiple of 321,732,915,473 is 185236260.
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.
321 x 732 x 915 x 473 = 101694706740
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.
321 : 1, 3, 107, 321
732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732
915 : 1, 3, 5, 15, 61, 183, 305, 915
473 : 1, 11, 43, 473
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,732,915,473, is 1.
Now, the common factors can be found like this.
321:3x 107
732:2x 2x 3x 61
915:3x 5x 61
473:11x 43
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 61 = 549
Therefore, the value for common factors is 549.
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 = 101694706740/(1x549)
LCM = 101694706740/549
LCM = 185236260
Thus, we can understand that the LCM of 321,732,915,473 is 185236260.
