Given numbers are 221,572,240,955
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 221,572,240,955 is 111437040.
Find LCM of 221,572,240,955 with Prime Factorization
| 2 | 221, 572, 240, 955 |
| 2 | 221, 286, 120, 955 |
| 5 | 221, 143, 60, 955 |
| 13 | 221, 143, 12, 191 |
| 17, 11, 12, 191 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 17 x 11 x 12 x 191 = 111437040
Therefore, the lowest common multiple of 221,572,240,955 is 111437040.
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.
221 x 572 x 240 x 955 = 28973630400
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.
221 : 1, 13, 17, 221
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
955 : 1, 5, 191, 955
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,572,240,955, is 1.
Now, the common factors can be found like this.
221:13x 17
572:2x 2x 11x 13
240:2x 2x 2x 2x 3x 5
955:5x 191
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 5x 13 = 260
Therefore, the value for common factors is 260.
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 = 28973630400/(1x260)
LCM = 28973630400/260
LCM = 111437040
Thus, we can understand that the LCM of 221,572,240,955 is 111437040.
