Given numbers are 537,399,910,661
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 537,399,910,661 is 6137206530.
Find LCM of 537,399,910,661 with Prime Factorization
| 3 | 537, 399, 910, 661 |
| 7 | 179, 133, 910, 661 |
| 179, 19, 130, 661 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 179 x 19 x 130 x 661 = 6137206530
Therefore, the lowest common multiple of 537,399,910,661 is 6137206530.
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.
537 x 399 x 910 x 661 = 128881337130
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.
537 : 1, 3, 179, 537
399 : 1, 3, 7, 19, 21, 57, 133, 399
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
661 : 1, 661
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 537,399,910,661, is 1.
Now, the common factors can be found like this.
537:3x 179
399:3x 7x 19
910:2x 5x 7x 13
661:661
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7 = 21
Therefore, the value for common factors is 21.
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 = 128881337130/(1x21)
LCM = 128881337130/21
LCM = 6137206530
Thus, we can understand that the LCM of 537,399,910,661 is 6137206530.
