Given numbers are 491,830,911,862,154
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 491,830,911,862,154 is 12320999978210.
Find LCM of 491,830,911,862,154 with Prime Factorization
2 | 491, 830, 911, 862, 154 |
491, 415, 911, 431, 77 |
Multiply the prime numbers at the bottom and the left side.
2 x 491 x 415 x 911 x 431 x 77 = 12320999978210
Therefore, the lowest common multiple of 491,830,911,862,154 is 12320999978210.
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.
491 x 830 x 911 x 862 x 154 = 49283999912840
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.
491 : 1, 491
830 : 1, 2, 5, 10, 83, 166, 415, 830
911 : 1, 911
862 : 1, 2, 431, 862
154 : 1, 2, 7, 11, 14, 22, 77, 154
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 491,830,911,862,154, is 1.
Now, the common factors can be found like this.
491:491
830:2x 5x 83
911:911
862:2x 431
154:2x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 49283999912840/(1x4)
LCM = 49283999912840/4
LCM = 12320999978210
Thus, we can understand that the LCM of 491,830,911,862,154 is 12320999978210.
