Find LCM of 900,702,440,720,521 with Prime Factorization
2 | 900, 702, 440, 720, 521 |
2 | 450, 351, 220, 360, 521 |
2 | 225, 351, 110, 180, 521 |
3 | 225, 351, 55, 90, 521 |
3 | 75, 117, 55, 30, 521 |
5 | 25, 39, 55, 10, 521 |
5, 39, 11, 2, 521 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 5 x 5 x 39 x 11 x 2 x 521 = 804632400
Therefore, the lowest common multiple of 900,702,440,720,521 is 804632400.
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.
900 x 702 x 440 x 720 x 521 = 104280359040000
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.
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
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
521 : 1, 521
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 900,702,440,720,521, is 1.
Now, the common factors can be found like this.
900:2x 2x 3x 3x 5x 5
702:2x 3x 3x 3x 13
440:2x 2x 2x 5x 11
720:2x 2x 2x 2x 3x 3x 5
521:521
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 2x 3x 3x 3x 3x 5x 5 = 129600
Therefore, the value for common factors is 129600.
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 = 104280359040000/(1x129600)
LCM = 104280359040000/129600
LCM = 804632400
Thus, we can understand that the LCM of 900,702,440,720,521 is 804632400.
