Given numbers are 472,845,655,393
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 472,845,655,393 is 156744120.
Find LCM of 472,845,655,393 with Prime Factorization
| 5 | 472, 845, 655, 393 |
| 131 | 472, 169, 131, 393 |
| 472, 169, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
5 x 131 x 472 x 169 x 1 x 3 = 156744120
Therefore, the lowest common multiple of 472,845,655,393 is 156744120.
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.
472 x 845 x 655 x 393 = 102667398600
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.
472 : 1, 2, 4, 8, 59, 118, 236, 472
845 : 1, 5, 13, 65, 169, 845
655 : 1, 5, 131, 655
393 : 1, 3, 131, 393
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 472,845,655,393, is 1.
Now, the common factors can be found like this.
472:2x 2x 2x 59
845:5x 13x 13
655:5x 131
393:3x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 131 = 655
Therefore, the value for common factors is 655.
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 = 102667398600/(1x655)
LCM = 102667398600/655
LCM = 156744120
Thus, we can understand that the LCM of 472,845,655,393 is 156744120.
