Given numbers are 451,803,221,702
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 451,803,221,702 is 392903082.
Find LCM of 451,803,221,702 with Prime Factorization
| 11 | 451, 803, 221, 702 |
| 13 | 41, 73, 221, 702 |
| 41, 73, 17, 54 |
Multiply the prime numbers at the bottom and the left side.
11 x 13 x 41 x 73 x 17 x 54 = 392903082
Therefore, the lowest common multiple of 451,803,221,702 is 392903082.
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.
451 x 803 x 221 x 702 = 56185140726
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.
451 : 1, 11, 41, 451
803 : 1, 11, 73, 803
221 : 1, 13, 17, 221
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 451,803,221,702, is 1.
Now, the common factors can be found like this.
451:11x 41
803:11x 73
221:13x 17
702:2x 3x 3x 3x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 13 = 143
Therefore, the value for common factors is 143.
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 = 56185140726/(1x143)
LCM = 56185140726/143
LCM = 392903082
Thus, we can understand that the LCM of 451,803,221,702 is 392903082.
