Given numbers are 180,542,955,210
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 180,542,955,210 is 65218860.
Find LCM of 180,542,955,210 with Prime Factorization
| 2 | 180, 542, 955, 210 |
| 3 | 90, 271, 955, 105 |
| 5 | 30, 271, 955, 35 |
| 6, 271, 191, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 6 x 271 x 191 x 7 = 65218860
Therefore, the lowest common multiple of 180,542,955,210 is 65218860.
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.
180 x 542 x 955 x 210 = 19565658000
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.
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
542 : 1, 2, 271, 542
955 : 1, 5, 191, 955
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 180,542,955,210, is 1.
Now, the common factors can be found like this.
180:2x 2x 3x 3x 5
542:2x 271
955:5x 191
210:2x 3x 5x 7
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 5x 5 = 300
Therefore, the value for common factors is 300.
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 = 19565658000/(1x300)
LCM = 19565658000/300
LCM = 65218860
Thus, we can understand that the LCM of 180,542,955,210 is 65218860.
