Find LCM of 392,624,759,845 with Prime Factorization
2 | 392, 624, 759, 845 |
2 | 196, 312, 759, 845 |
2 | 98, 156, 759, 845 |
3 | 49, 78, 759, 845 |
13 | 49, 26, 253, 845 |
49, 2, 253, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 13 x 49 x 2 x 253 x 65 = 502822320
Therefore, the lowest common multiple of 392,624,759,845 is 502822320.
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.
392 x 624 x 759 x 845 = 156880563840
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.
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
759 : 1, 3, 11, 23, 33, 69, 253, 759
845 : 1, 5, 13, 65, 169, 845
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,624,759,845, is 1.
Now, the common factors can be found like this.
392:2x 2x 2x 7x 7
624:2x 2x 2x 2x 3x 13
759:3x 11x 23
845:5x 13x 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 13 = 312
Therefore, the value for common factors is 312.
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 = 156880563840/(1x312)
LCM = 156880563840/312
LCM = 502822320
Thus, we can understand that the LCM of 392,624,759,845 is 502822320.
