Given numbers are 657,946,830,740,755
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 657,946,830,740,755 is 2882128033620.
Find LCM of 657,946,830,740,755 with Prime Factorization
| 2 | 657, 946, 830, 740, 755 |
| 5 | 657, 473, 415, 370, 755 |
| 657, 473, 83, 74, 151 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 657 x 473 x 83 x 74 x 151 = 2882128033620
Therefore, the lowest common multiple of 657,946,830,740,755 is 2882128033620.
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.
657 x 946 x 830 x 740 x 755 = 288212803362000
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.
657 : 1, 3, 9, 73, 219, 657
946 : 1, 2, 11, 22, 43, 86, 473, 946
830 : 1, 2, 5, 10, 83, 166, 415, 830
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
755 : 1, 5, 151, 755
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,946,830,740,755, is 1.
Now, the common factors can be found like this.
657:3x 3x 73
946:2x 11x 43
830:2x 5x 83
740:2x 2x 5x 37
755:5x 151
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 = 288212803362000/(1x100)
LCM = 288212803362000/100
LCM = 2882128033620
Thus, we can understand that the LCM of 657,946,830,740,755 is 2882128033620.
