Given numbers are 680,644,841,143,874
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 680,644,841,143,874 is 250161471560.
Find LCM of 680,644,841,143,874 with Prime Factorization
| 2 | 680, 644, 841, 143, 874 |
| 2 | 340, 322, 841, 143, 437 |
| 23 | 170, 161, 841, 143, 437 |
| 170, 7, 841, 143, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 23 x 170 x 7 x 841 x 143 x 19 = 250161471560
Therefore, the lowest common multiple of 680,644,841,143,874 is 250161471560.
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.
680 x 644 x 841 x 143 x 874 = 46029710767040
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.
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
841 : 1, 29, 841
143 : 1, 11, 13, 143
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 680,644,841,143,874, is 1.
Now, the common factors can be found like this.
680:2x 2x 2x 5x 17
644:2x 2x 7x 23
841:29x 29
143:11x 13
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 23 = 184
Therefore, the value for common factors is 184.
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 = 46029710767040/(1x184)
LCM = 46029710767040/184
LCM = 250161471560
Thus, we can understand that the LCM of 680,644,841,143,874 is 250161471560.
