Find LCM of 663,754,472,836,840 with Prime Factorization
| 2 | 663, 754, 472, 836, 840 |
| 2 | 663, 377, 236, 418, 420 |
| 2 | 663, 377, 118, 209, 210 |
| 3 | 663, 377, 59, 209, 105 |
| 13 | 221, 377, 59, 209, 35 |
| 17, 29, 59, 209, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 13 x 17 x 29 x 59 x 209 x 35 = 66384678360
Therefore, the lowest common multiple of 663,754,472,836,840 is 66384678360.
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.
663 x 754 x 472 x 836 x 840 = 165696157186560
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.
663 : 1, 3, 13, 17, 39, 51, 221, 663
754 : 1, 2, 13, 26, 29, 58, 377, 754
472 : 1, 2, 4, 8, 59, 118, 236, 472
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 663,754,472,836,840, is 1.
Now, the common factors can be found like this.
663:3x 13x 17
754:2x 13x 29
472:2x 2x 2x 59
836:2x 2x 11x 19
840:2x 2x 2x 3x 5x 7
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 2x 2x 3x 13 = 2496
Therefore, the value for common factors is 2496.
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 = 165696157186560/(1x2496)
LCM = 165696157186560/2496
LCM = 66384678360
Thus, we can understand that the LCM of 663,754,472,836,840 is 66384678360.
