Given numbers are 355,767,494,385,621
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 355,767,494,385,621 is 494754370110.
Find LCM of 355,767,494,385,621 with Prime Factorization
| 5 | 355, 767, 494, 385, 621 |
| 13 | 71, 767, 494, 77, 621 |
| 71, 59, 38, 77, 621 |
Multiply the prime numbers at the bottom and the left side.
5 x 13 x 71 x 59 x 38 x 77 x 621 = 494754370110
Therefore, the lowest common multiple of 355,767,494,385,621 is 494754370110.
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.
355 x 767 x 494 x 385 x 621 = 32159034057150
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.
355 : 1, 5, 71, 355
767 : 1, 13, 59, 767
494 : 1, 2, 13, 19, 26, 38, 247, 494
385 : 1, 5, 7, 11, 35, 55, 77, 385
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 355,767,494,385,621, is 1.
Now, the common factors can be found like this.
355:5x 71
767:13x 59
494:2x 13x 19
385:5x 7x 11
621:3x 3x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 13 = 65
Therefore, the value for common factors is 65.
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 = 32159034057150/(1x65)
LCM = 32159034057150/65
LCM = 494754370110
Thus, we can understand that the LCM of 355,767,494,385,621 is 494754370110.
