Given numbers are 681,249,154,234,651
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 681,249,154,234,651 is 10523791278.
Find LCM of 681,249,154,234,651 with Prime Factorization
| 2 | 681, 249, 154, 234, 651 |
| 3 | 681, 249, 77, 117, 651 |
| 7 | 227, 83, 77, 39, 217 |
| 227, 83, 11, 39, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 227 x 83 x 11 x 39 x 31 = 10523791278
Therefore, the lowest common multiple of 681,249,154,234,651 is 10523791278.
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.
681 x 249 x 154 x 234 x 651 = 3977993103084
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.
681 : 1, 3, 227, 681
249 : 1, 3, 83, 249
154 : 1, 2, 7, 11, 14, 22, 77, 154
234 : 1, 2, 3, 6, 9, 13, 18, 26, 39, 78, 117, 234
651 : 1, 3, 7, 21, 31, 93, 217, 651
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,249,154,234,651, is 1.
Now, the common factors can be found like this.
681:3x 227
249:3x 83
154:2x 7x 11
234:2x 3x 3x 13
651:3x 7x 31
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 3x 3x 7 = 378
Therefore, the value for common factors is 378.
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 = 3977993103084/(1x378)
LCM = 3977993103084/378
LCM = 10523791278
Thus, we can understand that the LCM of 681,249,154,234,651 is 10523791278.
