Given numbers are 622,572,655,455
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 622,572,655,455 is 815634820.
Find LCM of 622,572,655,455 with Prime Factorization
| 2 | 622, 572, 655, 455 |
| 5 | 311, 286, 655, 455 |
| 13 | 311, 286, 131, 91 |
| 311, 22, 131, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 311 x 22 x 131 x 7 = 815634820
Therefore, the lowest common multiple of 622,572,655,455 is 815634820.
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.
622 x 572 x 655 x 455 = 106032526600
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.
622 : 1, 2, 311, 622
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
655 : 1, 5, 131, 655
455 : 1, 5, 7, 13, 35, 65, 91, 455
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 622,572,655,455, is 1.
Now, the common factors can be found like this.
622:2x 311
572:2x 2x 11x 13
655:5x 131
455:5x 7x 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 5x 13 = 130
Therefore, the value for common factors is 130.
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 = 106032526600/(1x130)
LCM = 106032526600/130
LCM = 815634820
Thus, we can understand that the LCM of 622,572,655,455 is 815634820.
