Given numbers are 507,403,865,744,681
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 507,403,865,744,681 is 24688892280.
Find LCM of 507,403,865,744,681 with Prime Factorization
| 3 | 507, 403, 865, 744, 681 |
| 13 | 169, 403, 865, 248, 227 |
| 31 | 13, 31, 865, 248, 227 |
| 13, 1, 865, 8, 227 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 31 x 13 x 1 x 865 x 8 x 227 = 24688892280
Therefore, the lowest common multiple of 507,403,865,744,681 is 24688892280.
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 403 x 865 x 744 x 681 = 89546612299560
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
403 : 1, 13, 31, 403
865 : 1, 5, 173, 865
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
681 : 1, 3, 227, 681
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 507,403,865,744,681, is 1.
Now, the common factors can be found like this.
507:3x 13x 13
403:13x 31
865:5x 173
744:2x 2x 2x 3x 31
681:3x 227
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 13x 31 = 3627
Therefore, the value for common factors is 3627.
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 = 89546612299560/(1x3627)
LCM = 89546612299560/3627
LCM = 24688892280
Thus, we can understand that the LCM of 507,403,865,744,681 is 24688892280.
