Given numbers are 511,637,776,438
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 511,637,776,438 is 108254328.
Find LCM of 511,637,776,438 with Prime Factorization
| 2 | 511, 637, 776, 438 |
| 7 | 511, 637, 388, 219 |
| 73 | 73, 91, 388, 219 |
| 1, 91, 388, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 73 x 1 x 91 x 388 x 3 = 108254328
Therefore, the lowest common multiple of 511,637,776,438 is 108254328.
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.
511 x 637 x 776 x 438 = 110635923216
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.
511 : 1, 7, 73, 511
637 : 1, 7, 13, 49, 91, 637
776 : 1, 2, 4, 8, 97, 194, 388, 776
438 : 1, 2, 3, 6, 73, 146, 219, 438
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 511,637,776,438, is 1.
Now, the common factors can be found like this.
511:7x 73
637:7x 7x 13
776:2x 2x 2x 97
438:2x 3x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 73 = 1022
Therefore, the value for common factors is 1022.
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 = 110635923216/(1x1022)
LCM = 110635923216/1022
LCM = 108254328
Thus, we can understand that the LCM of 511,637,776,438 is 108254328.
