Given numbers are 222,238,357,621
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 222,238,357,621 is 5468526.
Find LCM of 222,238,357,621 with Prime Factorization
| 2 | 222, 238, 357, 621 |
| 3 | 111, 119, 357, 621 |
| 7 | 37, 119, 119, 207 |
| 17 | 37, 17, 17, 207 |
| 37, 1, 1, 207 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 17 x 37 x 1 x 1 x 207 = 5468526
Therefore, the lowest common multiple of 222,238,357,621 is 5468526.
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.
222 x 238 x 357 x 621 = 11713582692
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.
222 : 1, 2, 3, 6, 37, 74, 111, 222
238 : 1, 2, 7, 14, 17, 34, 119, 238
357 : 1, 3, 7, 17, 21, 51, 119, 357
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 222,238,357,621, is 1.
Now, the common factors can be found like this.
222:2x 3x 37
238:2x 7x 17
357:3x 7x 17
621:3x 3x 3x 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 3x 3x 7x 17 = 2142
Therefore, the value for common factors is 2142.
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 = 11713582692/(1x2142)
LCM = 11713582692/2142
LCM = 5468526
Thus, we can understand that the LCM of 222,238,357,621 is 5468526.
