Given numbers are 615,574,320,278,533
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 615,574,320,278,533 is 497864640.
Find LCM of 615,574,320,278,533 with Prime Factorization
| 2 | 615, 574, 320, 278, 533 |
| 5 | 615, 287, 160, 139, 533 |
| 41 | 123, 287, 32, 139, 533 |
| 3, 7, 32, 139, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 41 x 3 x 7 x 32 x 139 x 13 = 497864640
Therefore, the lowest common multiple of 615,574,320,278,533 is 497864640.
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.
615 x 574 x 320 x 278 x 533 = 16738209196800
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.
615 : 1, 3, 5, 15, 41, 123, 205, 615
574 : 1, 2, 7, 14, 41, 82, 287, 574
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
278 : 1, 2, 139, 278
533 : 1, 13, 41, 533
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,574,320,278,533, is 1.
Now, the common factors can be found like this.
615:3x 5x 41
574:2x 7x 41
320:2x 2x 2x 2x 2x 2x 5
278:2x 139
533:13x 41
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 41x 41 = 33620
Therefore, the value for common factors is 33620.
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 = 16738209196800/(1x33620)
LCM = 16738209196800/33620
LCM = 497864640
Thus, we can understand that the LCM of 615,574,320,278,533 is 497864640.
