Given numbers are 446,781,209,454
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 446,781,209,454 is 1502330038.
Find LCM of 446,781,209,454 with Prime Factorization
| 2 | 446, 781, 209, 454 |
| 11 | 223, 781, 209, 227 |
| 223, 71, 19, 227 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 223 x 71 x 19 x 227 = 1502330038
Therefore, the lowest common multiple of 446,781,209,454 is 1502330038.
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.
446 x 781 x 209 x 454 = 33051260836
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.
446 : 1, 2, 223, 446
781 : 1, 11, 71, 781
209 : 1, 11, 19, 209
454 : 1, 2, 227, 454
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 446,781,209,454, is 1.
Now, the common factors can be found like this.
446:2x 223
781:11x 71
209:11x 19
454:2x 227
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 = 33051260836/(1x22)
LCM = 33051260836/22
LCM = 1502330038
Thus, we can understand that the LCM of 446,781,209,454 is 1502330038.
