Given numbers are 231,371,721,491
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 231,371,721,491 is 619165239.
Find LCM of 231,371,721,491 with Prime Factorization
| 7 | 231, 371, 721, 491 |
| 33, 53, 103, 491 |
Multiply the prime numbers at the bottom and the left side.
7 x 33 x 53 x 103 x 491 = 619165239
Therefore, the lowest common multiple of 231,371,721,491 is 619165239.
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.
231 x 371 x 721 x 491 = 30339096711
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.
231 : 1, 3, 7, 11, 21, 33, 77, 231
371 : 1, 7, 53, 371
721 : 1, 7, 103, 721
491 : 1, 491
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 231,371,721,491, is 1.
Now, the common factors can be found like this.
231:3x 7x 11
371:7x 53
721:7x 103
491:491
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 7 = 49
Therefore, the value for common factors is 49.
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 = 30339096711/(1x49)
LCM = 30339096711/49
LCM = 619165239
Thus, we can understand that the LCM of 231,371,721,491 is 619165239.
