Given numbers are 637,412,578,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 637,412,578,221 is 75846316.
Find LCM of 637,412,578,221 with Prime Factorization
2 | 637, 412, 578, 221 |
13 | 637, 206, 289, 221 |
17 | 49, 206, 289, 17 |
49, 206, 1, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 17 x 49 x 206 x 1 x 17 = 75846316
Therefore, the lowest common multiple of 637,412,578,221 is 75846316.
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.
637 x 412 x 578 x 221 = 33524071672
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.
637 : 1, 7, 13, 49, 91, 637
412 : 1, 2, 4, 103, 206, 412
578 : 1, 2, 17, 34, 289, 578
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,412,578,221, is 1.
Now, the common factors can be found like this.
637:7x 7x 13
412:2x 2x 103
578:2x 17x 17
221:13x 17
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 = 33524071672/(1x442)
LCM = 33524071672/442
LCM = 75846316
Thus, we can understand that the LCM of 637,412,578,221 is 75846316.
