Find LCM of 749,159,583,404,420 with Prime Factorization
| 2 | 749, 159, 583, 404, 420 |
| 2 | 749, 159, 583, 202, 210 |
| 3 | 749, 159, 583, 101, 105 |
| 7 | 749, 53, 583, 101, 35 |
| 53 | 107, 53, 583, 101, 5 |
| 107, 1, 11, 101, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 53 x 107 x 1 x 11 x 101 x 5 = 2646202020
Therefore, the lowest common multiple of 749,159,583,404,420 is 2646202020.
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.
749 x 159 x 583 x 404 x 420 = 11780891393040
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.
749 : 1, 7, 107, 749
159 : 1, 3, 53, 159
583 : 1, 11, 53, 583
404 : 1, 2, 4, 101, 202, 404
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,159,583,404,420, is 1.
Now, the common factors can be found like this.
749:7x 107
159:3x 53
583:11x 53
404:2x 2x 101
420:2x 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 3x 7x 53 = 4452
Therefore, the value for common factors is 4452.
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 = 11780891393040/(1x4452)
LCM = 11780891393040/4452
LCM = 2646202020
Thus, we can understand that the LCM of 749,159,583,404,420 is 2646202020.
