The LCM of 615,820,172,564 is 4971660.
Find LCM of 615,820,172,564 with Prime Factorization
| 2 | 615, 820, 172, 564 |
| 2 | 615, 410, 86, 282 |
| 3 | 615, 205, 43, 141 |
| 5 | 205, 205, 43, 47 |
| 41 | 41, 41, 43, 47 |
| 1, 1, 43, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 41 x 1 x 1 x 43 x 47 = 4971660
Therefore, the lowest common multiple of 615,820,172,564 is 4971660.
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 820 x 172 x 564 = 48921134400
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
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
172 : 1, 2, 4, 43, 86, 172
564 : 1, 2, 3, 4, 6, 12, 47, 94, 141, 188, 282, 564
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,820,172,564, is 1.
Now, the common factors can be found like this.
615:3x 5x 41
820:2x 2x 5x 41
172:2x 2x 43
564:2x 2x 3x 47
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 2x 3x 5x 41 = 9840
Therefore, the value for common factors is 9840.
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 = 48921134400/(1x9840)
LCM = 48921134400/9840
LCM = 4971660
Thus, we can understand that the LCM of 615,820,172,564 is 4971660.
