The LCM of 641,228,836,506 is 36975444.
Find LCM of 641,228,836,506 with Prime Factorization
| 2 | 641, 228, 836, 506 |
| 2 | 641, 114, 418, 253 |
| 11 | 641, 57, 209, 253 |
| 19 | 641, 57, 19, 23 |
| 641, 3, 1, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 19 x 641 x 3 x 1 x 23 = 36975444
Therefore, the lowest common multiple of 641,228,836,506 is 36975444.
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.
641 x 228 x 836 x 506 = 61822942368
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.
641 : 1, 641
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
506 : 1, 2, 11, 22, 23, 46, 253, 506
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,228,836,506, is 1.
Now, the common factors can be found like this.
641:641
228:2x 2x 3x 19
836:2x 2x 11x 19
506:2x 11x 23
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 11x 19 = 1672
Therefore, the value for common factors is 1672.
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 = 61822942368/(1x1672)
LCM = 61822942368/1672
LCM = 36975444
Thus, we can understand that the LCM of 641,228,836,506 is 36975444.
