Given numbers are 869,658,906,988
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 869,658,906,988 is 127958995164.
Find LCM of 869,658,906,988 with Prime Factorization
2 | 869, 658, 906, 988 |
869, 329, 453, 494 |
Multiply the prime numbers at the bottom and the left side.
2 x 869 x 329 x 453 x 494 = 127958995164
Therefore, the lowest common multiple of 869,658,906,988 is 127958995164.
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.
869 x 658 x 906 x 988 = 511835980656
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.
869 : 1, 11, 79, 869
658 : 1, 2, 7, 14, 47, 94, 329, 658
906 : 1, 2, 3, 6, 151, 302, 453, 906
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 869,658,906,988, is 1.
Now, the common factors can be found like this.
869:11x 79
658:2x 7x 47
906:2x 3x 151
988:2x 2x 13x 19
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 = 511835980656/(1x4)
LCM = 511835980656/4
LCM = 127958995164
Thus, we can understand that the LCM of 869,658,906,988 is 127958995164.
