Find LCM of 312,392,931,941,782 with Prime Factorization
| 2 | 312, 392, 931, 941, 782 |
| 2 | 156, 196, 931, 941, 391 |
| 2 | 78, 98, 931, 941, 391 |
| 7 | 39, 49, 931, 941, 391 |
| 7 | 39, 7, 133, 941, 391 |
| 39, 1, 19, 941, 391 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 7 x 39 x 1 x 19 x 941 x 391 = 106873653432
Therefore, the lowest common multiple of 312,392,931,941,782 is 106873653432.
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.
312 x 392 x 931 x 941 x 782 = 83788944290688
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.
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
931 : 1, 7, 19, 49, 133, 931
941 : 1, 941
782 : 1, 2, 17, 23, 34, 46, 391, 782
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 312,392,931,941,782, is 1.
Now, the common factors can be found like this.
312:2x 2x 2x 3x 13
392:2x 2x 2x 7x 7
931:7x 7x 19
941:941
782:2x 17x 23
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 7x 7 = 784
Therefore, the value for common factors is 784.
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 = 83788944290688/(1x784)
LCM = 83788944290688/784
LCM = 106873653432
Thus, we can understand that the LCM of 312,392,931,941,782 is 106873653432.
