Find LCM of 100,260,798,124,931 with Prime Factorization
| 2 | 100, 260, 798, 124, 931 |
| 2 | 50, 130, 399, 62, 931 |
| 5 | 25, 65, 399, 31, 931 |
| 7 | 5, 13, 399, 31, 931 |
| 19 | 5, 13, 57, 31, 133 |
| 5, 13, 3, 31, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 19 x 5 x 13 x 3 x 31 x 7 = 112557900
Therefore, the lowest common multiple of 100,260,798,124,931 is 112557900.
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.
100 x 260 x 798 x 124 x 931 = 2395232112000
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.
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
124 : 1, 2, 4, 31, 62, 124
931 : 1, 7, 19, 49, 133, 931
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 100,260,798,124,931, is 1.
Now, the common factors can be found like this.
100:2x 2x 5x 5
260:2x 2x 5x 13
798:2x 3x 7x 19
124:2x 2x 31
931:7x 7x 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 2x 2x 2x 2x 5x 7x 19 = 21280
Therefore, the value for common factors is 21280.
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 = 2395232112000/(1x21280)
LCM = 2395232112000/21280
LCM = 112557900
Thus, we can understand that the LCM of 100,260,798,124,931 is 112557900.
