Find LCM of 749,810,632,896,392 with Prime Factorization
| 2 | 749, 810, 632, 896, 392 |
| 2 | 749, 405, 316, 448, 196 |
| 2 | 749, 405, 158, 224, 98 |
| 7 | 749, 405, 79, 112, 49 |
| 107, 405, 79, 16, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 107 x 405 x 79 x 16 x 7 = 21471972480
Therefore, the lowest common multiple of 749,810,632,896,392 is 21471972480.
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 810 x 632 x 896 x 392 = 134672211394560
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
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
632 : 1, 2, 4, 8, 79, 158, 316, 632
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,810,632,896,392, is 1.
Now, the common factors can be found like this.
749:7x 107
810:2x 3x 3x 3x 3x 5
632:2x 2x 2x 79
896:2x 2x 2x 2x 2x 2x 2x 7
392:2x 2x 2x 7x 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 2x 7x 7 = 6272
Therefore, the value for common factors is 6272.
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 = 134672211394560/(1x6272)
LCM = 134672211394560/6272
LCM = 21471972480
Thus, we can understand that the LCM of 749,810,632,896,392 is 21471972480.
