Given numbers are 975,637,338,286
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 975,637,338,286 is 13663650.
Find LCM of 975,637,338,286 with Prime Factorization
| 2 | 975, 637, 338, 286 |
| 13 | 975, 637, 169, 143 |
| 75, 49, 13, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 75 x 49 x 13 x 11 = 13663650
Therefore, the lowest common multiple of 975,637,338,286 is 13663650.
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.
975 x 637 x 338 x 286 = 60038078100
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.
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
637 : 1, 7, 13, 49, 91, 637
338 : 1, 2, 13, 26, 169, 338
286 : 1, 2, 11, 13, 22, 26, 143, 286
13 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 975,637,338,286, is 13.
Now, the common factors can be found like this.
975:3x 5x 5x 13
637:7x 7x 13
338:2x 13x 13
286:2x 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 13x 13 = 338
Therefore, the value for common factors is 338.
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 = 60038078100/(13x338)
LCM = 60038078100/4394
LCM = 13663650
Thus, we can understand that the LCM of 975,637,338,286 is 13663650.
