Given numbers are 551,994,798,766,245
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 551,994,798,766,245 is 22025514210.
Find LCM of 551,994,798,766,245 with Prime Factorization
| 2 | 551, 994, 798, 766, 245 |
| 7 | 551, 497, 399, 383, 245 |
| 19 | 551, 71, 57, 383, 35 |
| 29, 71, 3, 383, 35 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 19 x 29 x 71 x 3 x 383 x 35 = 22025514210
Therefore, the lowest common multiple of 551,994,798,766,245 is 22025514210.
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.
551 x 994 x 798 x 766 x 245 = 82023014918040
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.
551 : 1, 19, 29, 551
994 : 1, 2, 7, 14, 71, 142, 497, 994
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
766 : 1, 2, 383, 766
245 : 1, 5, 7, 35, 49, 245
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 551,994,798,766,245, is 1.
Now, the common factors can be found like this.
551:19x 29
994:2x 7x 71
798:2x 3x 7x 19
766:2x 383
245:5x 7x 7
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 7x 7x 19 = 3724
Therefore, the value for common factors is 3724.
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 = 82023014918040/(1x3724)
LCM = 82023014918040/3724
LCM = 22025514210
Thus, we can understand that the LCM of 551,994,798,766,245 is 22025514210.
