The LCM of 441,708,392,702 is 8117928.
Find LCM of 441,708,392,702 with Prime Factorization
| 2 | 441, 708, 392, 702 |
| 2 | 441, 354, 196, 351 |
| 3 | 441, 177, 98, 351 |
| 3 | 147, 59, 98, 117 |
| 7 | 49, 59, 98, 39 |
| 7 | 7, 59, 14, 39 |
| 1, 59, 2, 39 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 7 x 7 x 1 x 59 x 2 x 39 = 8117928
Therefore, the lowest common multiple of 441,708,392,702 is 8117928.
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.
441 x 708 x 392 x 702 = 85920149952
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.
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 441,708,392,702, is 1.
Now, the common factors can be found like this.
441:3x 3x 7x 7
708:2x 2x 3x 59
392:2x 2x 2x 7x 7
702:2x 3x 3x 3x 13
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 3x 3x 3x 7x 7 = 10584
Therefore, the value for common factors is 10584.
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 = 85920149952/(1x10584)
LCM = 85920149952/10584
LCM = 8117928
Thus, we can understand that the LCM of 441,708,392,702 is 8117928.
