Given numbers are 812,135,406,641
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 812,135,406,641 is 70266420.
Find LCM of 812,135,406,641 with Prime Factorization
2 | 812, 135, 406, 641 |
7 | 406, 135, 203, 641 |
29 | 58, 135, 29, 641 |
2, 135, 1, 641 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 29 x 2 x 135 x 1 x 641 = 70266420
Therefore, the lowest common multiple of 812,135,406,641 is 70266420.
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.
812 x 135 x 406 x 641 = 28528166520
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.
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
135 : 1, 3, 5, 9, 15, 27, 45, 135
406 : 1, 2, 7, 14, 29, 58, 203, 406
641 : 1, 641
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,135,406,641, is 1.
Now, the common factors can be found like this.
812:2x 2x 7x 29
135:3x 3x 3x 5
406:2x 7x 29
641:641
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 29 = 406
Therefore, the value for common factors is 406.
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 = 28528166520/(1x406)
LCM = 28528166520/406
LCM = 70266420
Thus, we can understand that the LCM of 812,135,406,641 is 70266420.
