Given numbers are 793,390,700,338
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 793,390,700,338 is 21648900.
Find LCM of 793,390,700,338 with Prime Factorization
| 2 | 793, 390, 700, 338 |
| 5 | 793, 195, 350, 169 |
| 13 | 793, 39, 70, 169 |
| 61, 3, 70, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 61 x 3 x 70 x 13 = 21648900
Therefore, the lowest common multiple of 793,390,700,338 is 21648900.
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.
793 x 390 x 700 x 338 = 73173282000
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.
793 : 1, 13, 61, 793
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
338 : 1, 2, 13, 26, 169, 338
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 793,390,700,338, is 1.
Now, the common factors can be found like this.
793:13x 61
390:2x 3x 5x 13
700:2x 2x 5x 5x 7
338:2x 13x 13
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 5x 13x 13 = 3380
Therefore, the value for common factors is 3380.
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 = 73173282000/(1x3380)
LCM = 73173282000/3380
LCM = 21648900
Thus, we can understand that the LCM of 793,390,700,338 is 21648900.
