Find LCM of 620,191,393,667,870 with Prime Factorization
| 2 | 620, 191, 393, 667, 870 |
| 3 | 310, 191, 393, 667, 435 |
| 5 | 310, 191, 131, 667, 145 |
| 29 | 62, 191, 131, 667, 29 |
| 62, 191, 131, 23, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 29 x 62 x 191 x 131 x 23 x 1 = 31041553020
Therefore, the lowest common multiple of 620,191,393,667,870 is 31041553020.
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.
620 x 191 x 393 x 667 x 870 = 27006151127400
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.
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
191 : 1, 191
393 : 1, 3, 131, 393
667 : 1, 23, 29, 667
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,191,393,667,870, is 1.
Now, the common factors can be found like this.
620:2x 2x 5x 31
191:191
393:3x 131
667:23x 29
870:2x 3x 5x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 29 = 870
Therefore, the value for common factors is 870.
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 = 27006151127400/(1x870)
LCM = 27006151127400/870
LCM = 31041553020
Thus, we can understand that the LCM of 620,191,393,667,870 is 31041553020.
