Find LCM of 776,420,441,391,266 with Prime Factorization
2 | 776, 420, 441, 391, 266 |
2 | 388, 210, 441, 391, 133 |
3 | 194, 105, 441, 391, 133 |
7 | 194, 35, 147, 391, 133 |
194, 5, 21, 391, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 194 x 5 x 21 x 391 x 19 = 12711613320
Therefore, the lowest common multiple of 776,420,441,391,266 is 12711613320.
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.
776 x 420 x 441 x 391 x 266 = 14948857264320
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.
776 : 1, 2, 4, 8, 97, 194, 388, 776
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
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
391 : 1, 17, 23, 391
266 : 1, 2, 7, 14, 19, 38, 133, 266
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 776,420,441,391,266, is 1.
Now, the common factors can be found like this.
776:2x 2x 2x 97
420:2x 2x 3x 5x 7
441:3x 3x 7x 7
391:17x 23
266:2x 7x 19
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 7x 7 = 1176
Therefore, the value for common factors is 1176.
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 = 14948857264320/(1x1176)
LCM = 14948857264320/1176
LCM = 12711613320
Thus, we can understand that the LCM of 776,420,441,391,266 is 12711613320.
