Find LCM of 570,855,646,689,380 with Prime Factorization
2 | 570, 855, 646, 689, 380 |
3 | 285, 855, 323, 689, 190 |
5 | 95, 285, 323, 689, 190 |
19 | 19, 57, 323, 689, 38 |
1, 3, 17, 689, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 19 x 1 x 3 x 17 x 689 x 2 = 40058460
Therefore, the lowest common multiple of 570,855,646,689,380 is 40058460.
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.
570 x 855 x 646 x 689 x 380 = 82428293142000
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.
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
646 : 1, 2, 17, 19, 34, 38, 323, 646
689 : 1, 13, 53, 689
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 570,855,646,689,380, is 1.
Now, the common factors can be found like this.
570:2x 3x 5x 19
855:3x 3x 5x 19
646:2x 17x 19
689:13x 53
380:2x 2x 5x 19
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 3x 5x 5x 19x 19x 19 = 2057700
Therefore, the value for common factors is 2057700.
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 = 82428293142000/(1x2057700)
LCM = 82428293142000/2057700
LCM = 40058460
Thus, we can understand that the LCM of 570,855,646,689,380 is 40058460.
