Given numbers are 343,669,203,222
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 343,669,203,222 is 492436182.
Find LCM of 343,669,203,222 with Prime Factorization
| 3 | 343, 669, 203, 222 |
| 7 | 343, 223, 203, 74 |
| 49, 223, 29, 74 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 49 x 223 x 29 x 74 = 492436182
Therefore, the lowest common multiple of 343,669,203,222 is 492436182.
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.
343 x 669 x 203 x 222 = 10341159822
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.
343 : 1, 7, 49, 343
669 : 1, 3, 223, 669
203 : 1, 7, 29, 203
222 : 1, 2, 3, 6, 37, 74, 111, 222
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 343,669,203,222, is 1.
Now, the common factors can be found like this.
343:7x 7x 7
669:3x 223
203:7x 29
222:2x 3x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7 = 21
Therefore, the value for common factors is 21.
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 = 10341159822/(1x21)
LCM = 10341159822/21
LCM = 492436182
Thus, we can understand that the LCM of 343,669,203,222 is 492436182.
