Given numbers are 115,421,802,156,411
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 115,421,802,156,411 is 414924877380.
Find LCM of 115,421,802,156,411 with Prime Factorization
| 2 | 115, 421, 802, 156, 411 |
| 3 | 115, 421, 401, 78, 411 |
| 115, 421, 401, 26, 137 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 115 x 421 x 401 x 26 x 137 = 414924877380
Therefore, the lowest common multiple of 115,421,802,156,411 is 414924877380.
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.
115 x 421 x 802 x 156 x 411 = 2489549264280
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.
115 : 1, 5, 23, 115
421 : 1, 421
802 : 1, 2, 401, 802
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
411 : 1, 3, 137, 411
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 115,421,802,156,411, is 1.
Now, the common factors can be found like this.
115:5x 23
421:421
802:2x 401
156:2x 2x 3x 13
411:3x 137
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 2489549264280/(1x6)
LCM = 2489549264280/6
LCM = 414924877380
Thus, we can understand that the LCM of 115,421,802,156,411 is 414924877380.
