Given numbers are 889,640,648,858
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 889,640,648,858 is 6590263680.
Find LCM of 889,640,648,858 with Prime Factorization
| 2 | 889, 640, 648, 858 |
| 2 | 889, 320, 324, 429 |
| 2 | 889, 160, 162, 429 |
| 3 | 889, 80, 81, 429 |
| 889, 80, 27, 143 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 889 x 80 x 27 x 143 = 6590263680
Therefore, the lowest common multiple of 889,640,648,858 is 6590263680.
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.
889 x 640 x 648 x 858 = 316332656640
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.
889 : 1, 7, 127, 889
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 889,640,648,858, is 1.
Now, the common factors can be found like this.
889:7x 127
640:2x 2x 2x 2x 2x 2x 2x 5
648:2x 2x 2x 3x 3x 3x 3
858:2x 3x 11x 13
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 2x 2x 3 = 48
Therefore, the value for common factors is 48.
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 = 316332656640/(1x48)
LCM = 316332656640/48
LCM = 6590263680
Thus, we can understand that the LCM of 889,640,648,858 is 6590263680.
