Given numbers are 515,855,321,781,506
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 515,855,321,781,506 is 338529081330.
Find LCM of 515,855,321,781,506 with Prime Factorization
3 | 515, 855, 321, 781, 506 |
5 | 515, 285, 107, 781, 506 |
11 | 103, 57, 107, 781, 506 |
103, 57, 107, 71, 46 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 103 x 57 x 107 x 71 x 46 = 338529081330
Therefore, the lowest common multiple of 515,855,321,781,506 is 338529081330.
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.
515 x 855 x 321 x 781 x 506 = 55857298419450
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.
515 : 1, 5, 103, 515
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
321 : 1, 3, 107, 321
781 : 1, 11, 71, 781
506 : 1, 2, 11, 22, 23, 46, 253, 506
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,855,321,781,506, is 1.
Now, the common factors can be found like this.
515:5x 103
855:3x 3x 5x 19
321:3x 107
781:11x 71
506:2x 11x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 11 = 165
Therefore, the value for common factors is 165.
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 = 55857298419450/(1x165)
LCM = 55857298419450/165
LCM = 338529081330
Thus, we can understand that the LCM of 515,855,321,781,506 is 338529081330.
