Given numbers are 408,734,221,65
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 408,734,221,65 is 9732840.
Find LCM of 408,734,221,65 with Prime Factorization
2 | 408, 734, 221, 65 |
13 | 204, 367, 221, 65 |
17 | 204, 367, 17, 5 |
12, 367, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 17 x 12 x 367 x 1 x 5 = 9732840
Therefore, the lowest common multiple of 408,734,221,65 is 9732840.
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.
408 x 734 x 221 x 65 = 4301915280
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.
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
734 : 1, 2, 367, 734
221 : 1, 13, 17, 221
65 : 1, 5, 13, 65
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 408,734,221,65, is 1.
Now, the common factors can be found like this.
408:2x 2x 2x 3x 17
734:2x 367
221:13x 17
65:5x 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 13x 17 = 442
Therefore, the value for common factors is 442.
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 = 4301915280/(1x442)
LCM = 4301915280/442
LCM = 9732840
Thus, we can understand that the LCM of 408,734,221,65 is 9732840.
