Given numbers are 671,814,820,880
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 671,814,820,880 is 81432560.
Find LCM of 671,814,820,880 with Prime Factorization
2 | 671, 814, 820, 880 |
2 | 671, 407, 410, 440 |
5 | 671, 407, 205, 220 |
11 | 671, 407, 41, 44 |
61, 37, 41, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 61 x 37 x 41 x 4 = 81432560
Therefore, the lowest common multiple of 671,814,820,880 is 81432560.
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.
671 x 814 x 820 x 880 = 394133590400
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.
671 : 1, 11, 61, 671
814 : 1, 2, 11, 22, 37, 74, 407, 814
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,814,820,880, is 1.
Now, the common factors can be found like this.
671:11x 61
814:2x 11x 37
820:2x 2x 5x 41
880:2x 2x 2x 2x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 5x 11x 11 = 4840
Therefore, the value for common factors is 4840.
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 = 394133590400/(1x4840)
LCM = 394133590400/4840
LCM = 81432560
Thus, we can understand that the LCM of 671,814,820,880 is 81432560.
