Given numbers are 518,143,924,722,821
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 518,143,924,722,821 is 131724757164.
Find LCM of 518,143,924,722,821 with Prime Factorization
| 2 | 518, 143, 924, 722, 821 |
| 7 | 259, 143, 462, 361, 821 |
| 11 | 37, 143, 66, 361, 821 |
| 37, 13, 6, 361, 821 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 37 x 13 x 6 x 361 x 821 = 131724757164
Therefore, the lowest common multiple of 518,143,924,722,821 is 131724757164.
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.
518 x 143 x 924 x 722 x 821 = 40571225206512
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.
518 : 1, 2, 7, 14, 37, 74, 259, 518
143 : 1, 11, 13, 143
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
722 : 1, 2, 19, 38, 361, 722
821 : 1, 821
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 518,143,924,722,821, is 1.
Now, the common factors can be found like this.
518:2x 7x 37
143:11x 13
924:2x 2x 3x 7x 11
722:2x 19x 19
821:821
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 7x 11 = 308
Therefore, the value for common factors is 308.
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 = 40571225206512/(1x308)
LCM = 40571225206512/308
LCM = 131724757164
Thus, we can understand that the LCM of 518,143,924,722,821 is 131724757164.
