Given numbers are 507,301,162,784
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 507,301,162,784 is 461483568.
Find LCM of 507,301,162,784 with Prime Factorization
| 2 | 507, 301, 162, 784 |
| 3 | 507, 301, 81, 392 |
| 7 | 169, 301, 27, 392 |
| 169, 43, 27, 56 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 169 x 43 x 27 x 56 = 461483568
Therefore, the lowest common multiple of 507,301,162,784 is 461483568.
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.
507 x 301 x 162 x 784 = 19382309856
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.
507 : 1, 3, 13, 39, 169, 507
301 : 1, 7, 43, 301
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 507,301,162,784, is 1.
Now, the common factors can be found like this.
507:3x 13x 13
301:7x 43
162:2x 3x 3x 3x 3
784:2x 2x 2x 2x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7 = 42
Therefore, the value for common factors is 42.
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 = 19382309856/(1x42)
LCM = 19382309856/42
LCM = 461483568
Thus, we can understand that the LCM of 507,301,162,784 is 461483568.
