Given numbers are 461,921,968,356,557
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 461,921,968,356,557 is 20374225787784.
Find LCM of 461,921,968,356,557 with Prime Factorization
| 2 | 461, 921, 968, 356, 557 |
| 2 | 461, 921, 484, 178, 557 |
| 461, 921, 242, 89, 557 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 461 x 921 x 242 x 89 x 557 = 20374225787784
Therefore, the lowest common multiple of 461,921,968,356,557 is 20374225787784.
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.
461 x 921 x 968 x 356 x 557 = 81496903151136
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.
461 : 1, 461
921 : 1, 3, 307, 921
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
356 : 1, 2, 4, 89, 178, 356
557 : 1, 557
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 461,921,968,356,557, is 1.
Now, the common factors can be found like this.
461:461
921:3x 307
968:2x 2x 2x 11x 11
356:2x 2x 89
557:557
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 81496903151136/(1x4)
LCM = 81496903151136/4
LCM = 20374225787784
Thus, we can understand that the LCM of 461,921,968,356,557 is 20374225787784.
