Given numbers are 291,808,655,628,738
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 291,808,655,628,738 is 2974064709240.
Find LCM of 291,808,655,628,738 with Prime Factorization
| 2 | 291, 808, 655, 628, 738 |
| 2 | 291, 404, 655, 314, 369 |
| 3 | 291, 202, 655, 157, 369 |
| 97, 202, 655, 157, 123 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 97 x 202 x 655 x 157 x 123 = 2974064709240
Therefore, the lowest common multiple of 291,808,655,628,738 is 2974064709240.
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 808 x 655 x 628 x 738 = 71377553021760
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
808 : 1, 2, 4, 8, 101, 202, 404, 808
655 : 1, 5, 131, 655
628 : 1, 2, 4, 157, 314, 628
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,808,655,628,738, is 1.
Now, the common factors can be found like this.
291:3x 97
808:2x 2x 2x 101
655:5x 131
628:2x 2x 157
738:2x 3x 3x 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 2x 2x 3 = 24
Therefore, the value for common factors is 24.
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 = 71377553021760/(1x24)
LCM = 71377553021760/24
LCM = 2974064709240
Thus, we can understand that the LCM of 291,808,655,628,738 is 2974064709240.
