Find LCM of 820,920,826,464,947 with Prime Factorization
2 | 820, 920, 826, 464, 947 |
2 | 410, 460, 413, 232, 947 |
2 | 205, 230, 413, 116, 947 |
5 | 205, 115, 413, 58, 947 |
41, 23, 413, 58, 947 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 41 x 23 x 413 x 58 x 947 = 855657001360
Therefore, the lowest common multiple of 820,920,826,464,947 is 855657001360.
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.
820 x 920 x 826 x 464 x 947 = 273810240435200
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.
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
826 : 1, 2, 7, 14, 59, 118, 413, 826
464 : 1, 2, 4, 8, 16, 29, 58, 116, 232, 464
947 : 1, 947
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,920,826,464,947, is 1.
Now, the common factors can be found like this.
820:2x 2x 5x 41
920:2x 2x 2x 5x 23
826:2x 7x 59
464:2x 2x 2x 2x 29
947:947
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 2x 2x 2x 5 = 320
Therefore, the value for common factors is 320.
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 = 273810240435200/(1x320)
LCM = 273810240435200/320
LCM = 855657001360
Thus, we can understand that the LCM of 820,920,826,464,947 is 855657001360.
