Given numbers are 875,715,975,821
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 875,715,975,821 is 308182875.
Find LCM of 875,715,975,821 with Prime Factorization
| 5 | 875, 715, 975, 821 |
| 5 | 175, 143, 195, 821 |
| 13 | 35, 143, 39, 821 |
| 35, 11, 3, 821 |
Multiply the prime numbers at the bottom and the left side.
5 x 5 x 13 x 35 x 11 x 3 x 821 = 308182875
Therefore, the lowest common multiple of 875,715,975,821 is 308182875.
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.
875 x 715 x 975 x 821 = 500797171875
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.
875 : 1, 5, 7, 25, 35, 125, 175, 875
715 : 1, 5, 11, 13, 55, 65, 143, 715
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
821 : 1, 821
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 875,715,975,821, is 1.
Now, the common factors can be found like this.
875:5x 5x 5x 7
715:5x 11x 13
975:3x 5x 5x 13
821:821
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 5x 13 = 1625
Therefore, the value for common factors is 1625.
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 = 500797171875/(1x1625)
LCM = 500797171875/1625
LCM = 308182875
Thus, we can understand that the LCM of 875,715,975,821 is 308182875.
