Given numbers are 291,840,799,674,393
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 291,840,799,674,393 is 2874080950440.
Find LCM of 291,840,799,674,393 with Prime Factorization
| 2 | 291, 840, 799, 674, 393 |
| 3 | 291, 420, 799, 337, 393 |
| 97, 140, 799, 337, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 97 x 140 x 799 x 337 x 131 = 2874080950440
Therefore, the lowest common multiple of 291,840,799,674,393 is 2874080950440.
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.
291 x 840 x 799 x 674 x 393 = 51733457107920
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.
291 : 1, 3, 97, 291
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
799 : 1, 17, 47, 799
674 : 1, 2, 337, 674
393 : 1, 3, 131, 393
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,840,799,674,393, is 1.
Now, the common factors can be found like this.
291:3x 97
840:2x 2x 2x 3x 5x 7
799:17x 47
674:2x 337
393:3x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 51733457107920/(1x18)
LCM = 51733457107920/18
LCM = 2874080950440
Thus, we can understand that the LCM of 291,840,799,674,393 is 2874080950440.
