Given numbers are 785,724,284,741,874
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 785,724,284,741,874 is 687721522020.
Find LCM of 785,724,284,741,874 with Prime Factorization
| 2 | 785, 724, 284, 741, 874 |
| 2 | 785, 362, 142, 741, 437 |
| 19 | 785, 181, 71, 741, 437 |
| 785, 181, 71, 39, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 785 x 181 x 71 x 39 x 23 = 687721522020
Therefore, the lowest common multiple of 785,724,284,741,874 is 687721522020.
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.
785 x 724 x 284 x 741 x 874 = 104533671347040
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.
785 : 1, 5, 157, 785
724 : 1, 2, 4, 181, 362, 724
284 : 1, 2, 4, 71, 142, 284
741 : 1, 3, 13, 19, 39, 57, 247, 741
874 : 1, 2, 19, 23, 38, 46, 437, 874
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,724,284,741,874, is 1.
Now, the common factors can be found like this.
785:5x 157
724:2x 2x 181
284:2x 2x 71
741:3x 13x 19
874:2x 19x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 19 = 152
Therefore, the value for common factors is 152.
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 = 104533671347040/(1x152)
LCM = 104533671347040/152
LCM = 687721522020
Thus, we can understand that the LCM of 785,724,284,741,874 is 687721522020.
