Given numbers are 920,491,698,949
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 920,491,698,949 is 149610115720.
Find LCM of 920,491,698,949 with Prime Factorization
2 | 920, 491, 698, 949 |
460, 491, 349, 949 |
Multiply the prime numbers at the bottom and the left side.
2 x 460 x 491 x 349 x 949 = 149610115720
Therefore, the lowest common multiple of 920,491,698,949 is 149610115720.
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.
920 x 491 x 698 x 949 = 299220231440
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.
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
491 : 1, 491
698 : 1, 2, 349, 698
949 : 1, 13, 73, 949
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,491,698,949, is 1.
Now, the common factors can be found like this.
920:2x 2x 2x 5x 23
491:491
698:2x 349
949:13x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 299220231440/(1x2)
LCM = 299220231440/2
LCM = 149610115720
Thus, we can understand that the LCM of 920,491,698,949 is 149610115720.
