Given numbers are 985,935,407,541,640
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 985,935,407,541,640 is 471940008320.
Find LCM of 985,935,407,541,640 with Prime Factorization
| 5 | 985, 935, 407, 541, 640 |
| 11 | 197, 187, 407, 541, 128 |
| 197, 17, 37, 541, 128 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 197 x 17 x 37 x 541 x 128 = 471940008320
Therefore, the lowest common multiple of 985,935,407,541,640 is 471940008320.
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.
985 x 935 x 407 x 541 x 640 = 129783502288000
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.
985 : 1, 5, 197, 985
935 : 1, 5, 11, 17, 55, 85, 187, 935
407 : 1, 11, 37, 407
541 : 1, 541
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 985,935,407,541,640, is 1.
Now, the common factors can be found like this.
985:5x 197
935:5x 11x 17
407:11x 37
541:541
640:2x 2x 2x 2x 2x 2x 2x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 11 = 275
Therefore, the value for common factors is 275.
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 = 129783502288000/(1x275)
LCM = 129783502288000/275
LCM = 471940008320
Thus, we can understand that the LCM of 985,935,407,541,640 is 471940008320.
