Given numbers are 932,861,286,490
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 932,861,286,490 is 4016272260.
Find LCM of 932,861,286,490 with Prime Factorization
| 2 | 932, 861, 286, 490 |
| 7 | 466, 861, 143, 245 |
| 466, 123, 143, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 466 x 123 x 143 x 35 = 4016272260
Therefore, the lowest common multiple of 932,861,286,490 is 4016272260.
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.
932 x 861 x 286 x 490 = 112455623280
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.
932 : 1, 2, 4, 233, 466, 932
861 : 1, 3, 7, 21, 41, 123, 287, 861
286 : 1, 2, 11, 13, 22, 26, 143, 286
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 932,861,286,490, is 1.
Now, the common factors can be found like this.
932:2x 2x 233
861:3x 7x 41
286:2x 11x 13
490:2x 5x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 7 = 28
Therefore, the value for common factors is 28.
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 = 112455623280/(1x28)
LCM = 112455623280/28
LCM = 4016272260
Thus, we can understand that the LCM of 932,861,286,490 is 4016272260.
