Given numbers are 291,520,343,679,902
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 291,520,343,679,902 is 23408144760.
Find LCM of 291,520,343,679,902 with Prime Factorization
| 2 | 291, 520, 343, 679, 902 |
| 7 | 291, 260, 343, 679, 451 |
| 97 | 291, 260, 49, 97, 451 |
| 3, 260, 49, 1, 451 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 97 x 3 x 260 x 49 x 1 x 451 = 23408144760
Therefore, the lowest common multiple of 291,520,343,679,902 is 23408144760.
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 520 x 343 x 679 x 902 = 31788260584080
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
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
343 : 1, 7, 49, 343
679 : 1, 7, 97, 679
902 : 1, 2, 11, 22, 41, 82, 451, 902
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,520,343,679,902, is 1.
Now, the common factors can be found like this.
291:3x 97
520:2x 2x 2x 5x 13
343:7x 7x 7
679:7x 97
902:2x 11x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 97 = 1358
Therefore, the value for common factors is 1358.
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 = 31788260584080/(1x1358)
LCM = 31788260584080/1358
LCM = 23408144760
Thus, we can understand that the LCM of 291,520,343,679,902 is 23408144760.
