Given numbers are 721,564,299,914,393
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,564,299,914,393 is 7279022348052.
Find LCM of 721,564,299,914,393 with Prime Factorization
| 2 | 721, 564, 299, 914, 393 |
| 3 | 721, 282, 299, 457, 393 |
| 721, 94, 299, 457, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 721 x 94 x 299 x 457 x 131 = 7279022348052
Therefore, the lowest common multiple of 721,564,299,914,393 is 7279022348052.
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.
721 x 564 x 299 x 914 x 393 = 43674134088312
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.
721 : 1, 7, 103, 721
564 : 1, 2, 3, 4, 6, 12, 47, 94, 141, 188, 282, 564
299 : 1, 13, 23, 299
914 : 1, 2, 457, 914
393 : 1, 3, 131, 393
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,564,299,914,393, is 1.
Now, the common factors can be found like this.
721:7x 103
564:2x 2x 3x 47
299:13x 23
914:2x 457
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 3 = 6
Therefore, the value for common factors is 6.
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 = 43674134088312/(1x6)
LCM = 43674134088312/6
LCM = 7279022348052
Thus, we can understand that the LCM of 721,564,299,914,393 is 7279022348052.
