Given numbers are 437,221,646,144
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 437,221,646,144 is 13907088.
Find LCM of 437,221,646,144 with Prime Factorization
| 2 | 437, 221, 646, 144 |
| 17 | 437, 221, 323, 72 |
| 19 | 437, 13, 19, 72 |
| 23, 13, 1, 72 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 19 x 23 x 13 x 1 x 72 = 13907088
Therefore, the lowest common multiple of 437,221,646,144 is 13907088.
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.
437 x 221 x 646 x 144 = 8983978848
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.
437 : 1, 19, 23, 437
221 : 1, 13, 17, 221
646 : 1, 2, 17, 19, 34, 38, 323, 646
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 437,221,646,144, is 1.
Now, the common factors can be found like this.
437:19x 23
221:13x 17
646:2x 17x 19
144:2x 2x 2x 2x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17x 19 = 646
Therefore, the value for common factors is 646.
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 = 8983978848/(1x646)
LCM = 8983978848/646
LCM = 13907088
Thus, we can understand that the LCM of 437,221,646,144 is 13907088.
