Given numbers are 793,247,661,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 793,247,661,442 is 338615758.
Find LCM of 793,247,661,442 with Prime Factorization
| 13 | 793, 247, 661, 442 |
| 61, 19, 661, 34 |
Multiply the prime numbers at the bottom and the left side.
13 x 61 x 19 x 661 x 34 = 338615758
Therefore, the lowest common multiple of 793,247,661,442 is 338615758.
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 247 x 661 x 442 = 57226063102
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
247 : 1, 13, 19, 247
661 : 1, 661
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 793,247,661,442, is 1.
Now, the common factors can be found like this.
793:13x 61
247:13x 19
661:661
442:2x 13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 13 = 169
Therefore, the value for common factors is 169.
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 = 57226063102/(1x169)
LCM = 57226063102/169
LCM = 338615758
Thus, we can understand that the LCM of 793,247,661,442 is 338615758.
