Given numbers are 991,466,840,298
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,466,840,298 is 28899819480.
Find LCM of 991,466,840,298 with Prime Factorization
| 2 | 991, 466, 840, 298 |
| 991, 233, 420, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 991 x 233 x 420 x 149 = 28899819480
Therefore, the lowest common multiple of 991,466,840,298 is 28899819480.
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.
991 x 466 x 840 x 298 = 115599277920
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.
991 : 1, 991
466 : 1, 2, 233, 466
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
298 : 1, 2, 149, 298
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,466,840,298, is 1.
Now, the common factors can be found like this.
991:991
466:2x 233
840:2x 2x 2x 3x 5x 7
298:2x 149
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 = 115599277920/(1x4)
LCM = 115599277920/4
LCM = 28899819480
Thus, we can understand that the LCM of 991,466,840,298 is 28899819480.
