Given numbers are 605,697,621,221,709
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 605,697,621,221,709 is 2413622470545.
Find LCM of 605,697,621,221,709 with Prime Factorization
17 | 605, 697, 621, 221, 709 |
605, 41, 621, 13, 709 |
Multiply the prime numbers at the bottom and the left side.
17 x 605 x 41 x 621 x 13 x 709 = 2413622470545
Therefore, the lowest common multiple of 605,697,621,221,709 is 2413622470545.
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.
605 x 697 x 621 x 221 x 709 = 41031581999265
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.
605 : 1, 5, 11, 55, 121, 605
697 : 1, 17, 41, 697
621 : 1, 3, 9, 23, 27, 69, 207, 621
221 : 1, 13, 17, 221
709 : 1, 709
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 605,697,621,221,709, is 1.
Now, the common factors can be found like this.
605:5x 11x 11
697:17x 41
621:3x 3x 3x 23
221:13x 17
709:709
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17 = 17
Therefore, the value for common factors is 17.
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 = 41031581999265/(1x17)
LCM = 41031581999265/17
LCM = 2413622470545
Thus, we can understand that the LCM of 605,697,621,221,709 is 2413622470545.
