Given numbers are 730,946,819,320
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 730,946,819,320 is 9049360320.
Find LCM of 730,946,819,320 with Prime Factorization
| 2 | 730, 946, 819, 320 |
| 5 | 365, 473, 819, 160 |
| 73, 473, 819, 32 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 73 x 473 x 819 x 32 = 9049360320
Therefore, the lowest common multiple of 730,946,819,320 is 9049360320.
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.
730 x 946 x 819 x 320 = 180987206400
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.
730 : 1, 2, 5, 10, 73, 146, 365, 730
946 : 1, 2, 11, 22, 43, 86, 473, 946
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 730,946,819,320, is 1.
Now, the common factors can be found like this.
730:2x 5x 73
946:2x 11x 43
819:3x 3x 7x 13
320:2x 2x 2x 2x 2x 2x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 5 = 20
Therefore, the value for common factors is 20.
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 = 180987206400/(1x20)
LCM = 180987206400/20
LCM = 9049360320
Thus, we can understand that the LCM of 730,946,819,320 is 9049360320.
