Given numbers are 462,403,315,242,154
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 462,403,315,242,154 is 30720690.
Find LCM of 462,403,315,242,154 with Prime Factorization
| 2 | 462, 403, 315, 242, 154 |
| 3 | 231, 403, 315, 121, 77 |
| 7 | 77, 403, 105, 121, 77 |
| 11 | 11, 403, 15, 121, 11 |
| 1, 403, 15, 1, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 1 x 403 x 15 x 1 x 11 = 30720690
Therefore, the lowest common multiple of 462,403,315,242,154 is 30720690.
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.
462 x 403 x 315 x 242 x 154 = 2185715652120
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.
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
403 : 1, 13, 31, 403
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
242 : 1, 2, 11, 22, 121, 242
154 : 1, 2, 7, 11, 14, 22, 77, 154
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 462,403,315,242,154, is 1.
Now, the common factors can be found like this.
462:2x 3x 7x 11
403:13x 31
315:3x 3x 5x 7
242:2x 11x 11
154:2x 7x 11
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 3x 7x 7x 11x 11 = 71148
Therefore, the value for common factors is 71148.
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 = 2185715652120/(1x71148)
LCM = 2185715652120/71148
LCM = 30720690
Thus, we can understand that the LCM of 462,403,315,242,154 is 30720690.
