Find LCM of 423,900,620,255,575 with Prime Factorization
2 | 423, 900, 620, 255, 575 |
2 | 423, 450, 310, 255, 575 |
3 | 423, 225, 155, 255, 575 |
3 | 141, 75, 155, 85, 575 |
5 | 47, 25, 155, 85, 575 |
5 | 47, 5, 31, 17, 115 |
47, 1, 31, 17, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 5 x 47 x 1 x 31 x 17 x 23 = 512718300
Therefore, the lowest common multiple of 423,900,620,255,575 is 512718300.
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.
423 x 900 x 620 x 255 x 575 = 34608485250000
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.
423 : 1, 3, 9, 47, 141, 423
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
255 : 1, 3, 5, 15, 17, 51, 85, 255
575 : 1, 5, 23, 25, 115, 575
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,900,620,255,575, is 1.
Now, the common factors can be found like this.
423:3x 3x 47
900:2x 2x 3x 3x 5x 5
620:2x 2x 5x 31
255:3x 5x 17
575:5x 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 3x 3x 3x 5x 5x 5x 5 = 67500
Therefore, the value for common factors is 67500.
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 = 34608485250000/(1x67500)
LCM = 34608485250000/67500
LCM = 512718300
Thus, we can understand that the LCM of 423,900,620,255,575 is 512718300.
