Given numbers are 955,120,860,553
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 955,120,860,553 is 545014680.
Find LCM of 955,120,860,553 with Prime Factorization
| 2 | 955, 120, 860, 553 |
| 2 | 955, 60, 430, 553 |
| 5 | 955, 30, 215, 553 |
| 191, 6, 43, 553 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 191 x 6 x 43 x 553 = 545014680
Therefore, the lowest common multiple of 955,120,860,553 is 545014680.
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.
955 x 120 x 860 x 553 = 54501468000
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.
955 : 1, 5, 191, 955
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
553 : 1, 7, 79, 553
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 955,120,860,553, is 1.
Now, the common factors can be found like this.
955:5x 191
120:2x 2x 2x 3x 5
860:2x 2x 5x 43
553:7x 79
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 5 = 100
Therefore, the value for common factors is 100.
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 = 54501468000/(1x100)
LCM = 54501468000/100
LCM = 545014680
Thus, we can understand that the LCM of 955,120,860,553 is 545014680.
