Find LCM of 688,903,944,808 with Prime Factorization
2 | 688, 903, 944, 808 |
2 | 344, 903, 472, 404 |
2 | 172, 903, 236, 202 |
2 | 86, 903, 118, 101 |
43 | 43, 903, 59, 101 |
1, 21, 59, 101 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 43 x 1 x 21 x 59 x 101 = 86095632
Therefore, the lowest common multiple of 688,903,944,808 is 86095632.
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.
688 x 903 x 944 x 808 = 473870358528
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.
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
903 : 1, 3, 7, 21, 43, 129, 301, 903
944 : 1, 2, 4, 8, 16, 59, 118, 236, 472, 944
808 : 1, 2, 4, 8, 101, 202, 404, 808
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,903,944,808, is 1.
Now, the common factors can be found like this.
688:2x 2x 2x 2x 43
903:3x 7x 43
944:2x 2x 2x 2x 59
808:2x 2x 2x 101
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 2x 2x 2x 43 = 5504
Therefore, the value for common factors is 5504.
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 = 473870358528/(1x5504)
LCM = 473870358528/5504
LCM = 86095632
Thus, we can understand that the LCM of 688,903,944,808 is 86095632.
