Find LCM of 668,785,338,572,920 with Prime Factorization
2 | 668, 785, 338, 572, 920 |
2 | 334, 785, 169, 286, 460 |
5 | 167, 785, 169, 143, 230 |
13 | 167, 157, 169, 143, 46 |
167, 157, 13, 11, 46 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 167 x 157 x 13 x 11 x 46 = 44841831320
Therefore, the lowest common multiple of 668,785,338,572,920 is 44841831320.
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.
668 x 785 x 338 x 572 x 920 = 93271009145600
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.
668 : 1, 2, 4, 167, 334, 668
785 : 1, 5, 157, 785
338 : 1, 2, 13, 26, 169, 338
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,785,338,572,920, is 1.
Now, the common factors can be found like this.
668:2x 2x 167
785:5x 157
338:2x 13x 13
572:2x 2x 11x 13
920:2x 2x 2x 5x 23
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 5x 13 = 2080
Therefore, the value for common factors is 2080.
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 = 93271009145600/(1x2080)
LCM = 93271009145600/2080
LCM = 44841831320
Thus, we can understand that the LCM of 668,785,338,572,920 is 44841831320.
