Given numbers are 320,466,505,472
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 320,466,505,472 is 444303040.
Find LCM of 320,466,505,472 with Prime Factorization
| 2 | 320, 466, 505, 472 |
| 2 | 160, 233, 505, 236 |
| 2 | 80, 233, 505, 118 |
| 5 | 40, 233, 505, 59 |
| 8, 233, 101, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 8 x 233 x 101 x 59 = 444303040
Therefore, the lowest common multiple of 320,466,505,472 is 444303040.
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.
320 x 466 x 505 x 472 = 35544243200
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.
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
466 : 1, 2, 233, 466
505 : 1, 5, 101, 505
472 : 1, 2, 4, 8, 59, 118, 236, 472
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 320,466,505,472, is 1.
Now, the common factors can be found like this.
320:2x 2x 2x 2x 2x 2x 5
466:2x 233
505:5x 101
472:2x 2x 2x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 5 = 80
Therefore, the value for common factors is 80.
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 = 35544243200/(1x80)
LCM = 35544243200/80
LCM = 444303040
Thus, we can understand that the LCM of 320,466,505,472 is 444303040.
