Given numbers are 542,869,912,121
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 542,869,912,121 is 2362525968.
Find LCM of 542,869,912,121 with Prime Factorization
| 2 | 542, 869, 912, 121 |
| 11 | 271, 869, 456, 121 |
| 271, 79, 456, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 271 x 79 x 456 x 11 = 2362525968
Therefore, the lowest common multiple of 542,869,912,121 is 2362525968.
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.
542 x 869 x 912 x 121 = 51975571296
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.
542 : 1, 2, 271, 542
869 : 1, 11, 79, 869
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 542,869,912,121, is 1.
Now, the common factors can be found like this.
542:2x 271
869:11x 79
912:2x 2x 2x 2x 3x 19
121:11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 51975571296/(1x22)
LCM = 51975571296/22
LCM = 2362525968
Thus, we can understand that the LCM of 542,869,912,121 is 2362525968.
