Given numbers are 731,855,321,247,602
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 731,855,321,247,602 is 12171347370.
Find LCM of 731,855,321,247,602 with Prime Factorization
| 3 | 731, 855, 321, 247, 602 |
| 19 | 731, 285, 107, 247, 602 |
| 43 | 731, 15, 107, 13, 602 |
| 17, 15, 107, 13, 14 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 43 x 17 x 15 x 107 x 13 x 14 = 12171347370
Therefore, the lowest common multiple of 731,855,321,247,602 is 12171347370.
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.
731 x 855 x 321 x 247 x 602 = 29831972403870
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.
731 : 1, 17, 43, 731
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
321 : 1, 3, 107, 321
247 : 1, 13, 19, 247
602 : 1, 2, 7, 14, 43, 86, 301, 602
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,855,321,247,602, is 1.
Now, the common factors can be found like this.
731:17x 43
855:3x 3x 5x 19
321:3x 107
247:13x 19
602:2x 7x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 19x 43 = 2451
Therefore, the value for common factors is 2451.
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 = 29831972403870/(1x2451)
LCM = 29831972403870/2451
LCM = 12171347370
Thus, we can understand that the LCM of 731,855,321,247,602 is 12171347370.
