Given numbers are 722,836,456,663
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 722,836,456,663 is 21062184.
Find LCM of 722,836,456,663 with Prime Factorization
| 2 | 722, 836, 456, 663 |
| 2 | 361, 418, 228, 663 |
| 3 | 361, 209, 114, 663 |
| 19 | 361, 209, 38, 221 |
| 19, 11, 2, 221 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 19 x 19 x 11 x 2 x 221 = 21062184
Therefore, the lowest common multiple of 722,836,456,663 is 21062184.
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.
722 x 836 x 456 x 663 = 182482762176
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.
722 : 1, 2, 19, 38, 361, 722
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
663 : 1, 3, 13, 17, 39, 51, 221, 663
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,836,456,663, is 1.
Now, the common factors can be found like this.
722:2x 19x 19
836:2x 2x 11x 19
456:2x 2x 2x 3x 19
663:3x 13x 17
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 3x 19x 19 = 8664
Therefore, the value for common factors is 8664.
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 = 182482762176/(1x8664)
LCM = 182482762176/8664
LCM = 21062184
Thus, we can understand that the LCM of 722,836,456,663 is 21062184.
