Find LCM of 620,270,689,897,422 with Prime Factorization
2 | 620, 270, 689, 897, 422 |
3 | 310, 135, 689, 897, 211 |
5 | 310, 45, 689, 299, 211 |
13 | 62, 9, 689, 299, 211 |
62, 9, 53, 23, 211 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 62 x 9 x 53 x 23 x 211 = 55973822580
Therefore, the lowest common multiple of 620,270,689,897,422 is 55973822580.
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 270 x 689 x 897 x 422 = 43659581612400
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
270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
689 : 1, 13, 53, 689
897 : 1, 3, 13, 23, 39, 69, 299, 897
422 : 1, 2, 211, 422
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,270,689,897,422, is 1.
Now, the common factors can be found like this.
620:2x 2x 5x 31
270:2x 3x 3x 3x 5
689:13x 53
897:3x 13x 23
422:2x 211
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 13 = 780
Therefore, the value for common factors is 780.
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 = 43659581612400/(1x780)
LCM = 43659581612400/780
LCM = 55973822580
Thus, we can understand that the LCM of 620,270,689,897,422 is 55973822580.
