Given numbers are 615,130,342,603,387
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 615,130,342,603,387 is 2625829830.
Find LCM of 615,130,342,603,387 with Prime Factorization
| 2 | 615, 130, 342, 603, 387 |
| 3 | 615, 65, 171, 603, 387 |
| 3 | 205, 65, 57, 201, 129 |
| 5 | 205, 65, 19, 67, 43 |
| 41, 13, 19, 67, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 41 x 13 x 19 x 67 x 43 = 2625829830
Therefore, the lowest common multiple of 615,130,342,603,387 is 2625829830.
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 130 x 342 x 603 x 387 = 6380766486900
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
130 : 1, 2, 5, 10, 13, 26, 65, 130
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
603 : 1, 3, 9, 67, 201, 603
387 : 1, 3, 9, 43, 129, 387
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,130,342,603,387, is 1.
Now, the common factors can be found like this.
615:3x 5x 41
130:2x 5x 13
342:2x 3x 3x 19
603:3x 3x 67
387:3x 3x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3x 3x 5 = 2430
Therefore, the value for common factors is 2430.
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 = 6380766486900/(1x2430)
LCM = 6380766486900/2430
LCM = 2625829830
Thus, we can understand that the LCM of 615,130,342,603,387 is 2625829830.
