Given numbers are 526,640,691,248,131
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 526,640,691,248,131 is 472331336320.
Find LCM of 526,640,691,248,131 with Prime Factorization
| 2 | 526, 640, 691, 248, 131 |
| 2 | 263, 320, 691, 124, 131 |
| 2 | 263, 160, 691, 62, 131 |
| 263, 80, 691, 31, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 263 x 80 x 691 x 31 x 131 = 472331336320
Therefore, the lowest common multiple of 526,640,691,248,131 is 472331336320.
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.
526 x 640 x 691 x 248 x 131 = 7557301381120
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.
526 : 1, 2, 263, 526
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
691 : 1, 691
248 : 1, 2, 4, 8, 31, 62, 124, 248
131 : 1, 131
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 526,640,691,248,131, is 1.
Now, the common factors can be found like this.
526:2x 263
640:2x 2x 2x 2x 2x 2x 2x 5
691:691
248:2x 2x 2x 31
131:131
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 2x 2 = 16
Therefore, the value for common factors is 16.
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 = 7557301381120/(1x16)
LCM = 7557301381120/16
LCM = 472331336320
Thus, we can understand that the LCM of 526,640,691,248,131 is 472331336320.
