Find LCM of 638,986,875,210,103 with Prime Factorization
2 | 638, 986, 875, 210, 103 |
5 | 319, 493, 875, 105, 103 |
7 | 319, 493, 175, 21, 103 |
29 | 319, 493, 25, 3, 103 |
11, 17, 25, 3, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 29 x 11 x 17 x 25 x 3 x 103 = 2932487250
Therefore, the lowest common multiple of 638,986,875,210,103 is 2932487250.
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.
638 x 986 x 875 x 210 x 103 = 11905898235000
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.
638 : 1, 2, 11, 22, 29, 58, 319, 638
986 : 1, 2, 17, 29, 34, 58, 493, 986
875 : 1, 5, 7, 25, 35, 125, 175, 875
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
103 : 1, 103
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,986,875,210,103, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
986:2x 17x 29
875:5x 5x 5x 7
210:2x 3x 5x 7
103:103
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 5x 7x 29 = 4060
Therefore, the value for common factors is 4060.
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 = 11905898235000/(1x4060)
LCM = 11905898235000/4060
LCM = 2932487250
Thus, we can understand that the LCM of 638,986,875,210,103 is 2932487250.
