The LCM of 266,455,698,945,778 is 63377307630.
Find LCM of 266,455,698,945,778 with Prime Factorization
| 2 | 266, 455, 698, 945, 778 |
| 5 | 133, 455, 349, 945, 389 |
| 7 | 133, 91, 349, 189, 389 |
| 19, 13, 349, 27, 389 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 19 x 13 x 349 x 27 x 389 = 63377307630
Therefore, the lowest common multiple of 266,455,698,945,778 is 63377307630.
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.
266 x 455 x 698 x 945 x 778 = 62109761477400
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.
266 : 1, 2, 7, 14, 19, 38, 133, 266
455 : 1, 5, 7, 13, 35, 65, 91, 455
698 : 1, 2, 349, 698
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
778 : 1, 2, 389, 778
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 266,455,698,945,778, is 1.
Now, the common factors can be found like this.
266:2x 7x 19
455:5x 7x 13
698:2x 349
945:3x 3x 3x 5x 7
778:2x 389
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 5x 7x 7 = 980
Therefore, the value for common factors is 980.
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 = 62109761477400/(1x980)
LCM = 62109761477400/980
LCM = 63377307630
Thus, we can understand that the LCM of 266,455,698,945,778 is 63377307630.
