Given numbers are 689,785,981,501,521
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 689,785,981,501,521 is 46164919274955.
Find LCM of 689,785,981,501,521 with Prime Factorization
| 3 | 689, 785, 981, 501, 521 |
| 689, 785, 327, 167, 521 |
Multiply the prime numbers at the bottom and the left side.
3 x 689 x 785 x 327 x 167 x 521 = 46164919274955
Therefore, the lowest common multiple of 689,785,981,501,521 is 46164919274955.
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.
689 x 785 x 981 x 501 x 521 = 138494757824865
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.
689 : 1, 13, 53, 689
785 : 1, 5, 157, 785
981 : 1, 3, 9, 109, 327, 981
501 : 1, 3, 167, 501
521 : 1, 521
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,785,981,501,521, is 1.
Now, the common factors can be found like this.
689:13x 53
785:5x 157
981:3x 3x 109
501:3x 167
521:521
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 138494757824865/(1x3)
LCM = 138494757824865/3
LCM = 46164919274955
Thus, we can understand that the LCM of 689,785,981,501,521 is 46164919274955.
