Given numbers are 875,630,810,429
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 875,630,810,429 is 20270250.
Find LCM of 875,630,810,429 with Prime Factorization
| 2 | 875, 630, 810, 429 |
| 3 | 875, 315, 405, 429 |
| 3 | 875, 105, 135, 143 |
| 5 | 875, 35, 45, 143 |
| 7 | 175, 7, 9, 143 |
| 25, 1, 9, 143 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 7 x 25 x 1 x 9 x 143 = 20270250
Therefore, the lowest common multiple of 875,630,810,429 is 20270250.
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 630 x 810 x 429 = 191553862500
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
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
429 : 1, 3, 11, 13, 33, 39, 143, 429
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 875,630,810,429, is 1.
Now, the common factors can be found like this.
875:5x 5x 5x 7
630:2x 3x 3x 5x 7
810:2x 3x 3x 3x 3x 5
429:3x 11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 5x 5x 7 = 9450
Therefore, the value for common factors is 9450.
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 = 191553862500/(1x9450)
LCM = 191553862500/9450
LCM = 20270250
Thus, we can understand that the LCM of 875,630,810,429 is 20270250.
