The LCM of 901,920,299,450,690 is 484918200.
Find LCM of 901,920,299,450,690 with Prime Factorization
| 2 | 901, 920, 299, 450, 690 |
| 3 | 901, 460, 299, 225, 345 |
| 5 | 901, 460, 299, 75, 115 |
| 23 | 901, 92, 299, 15, 23 |
| 901, 4, 13, 15, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 23 x 901 x 4 x 13 x 15 x 1 = 484918200
Therefore, the lowest common multiple of 901,920,299,450,690 is 484918200.
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.
901 x 920 x 299 x 450 x 690 = 76956518340000
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.
901 : 1, 17, 53, 901
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
299 : 1, 13, 23, 299
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 901,920,299,450,690, is 1.
Now, the common factors can be found like this.
901:17x 53
920:2x 2x 2x 5x 23
299:13x 23
450:2x 3x 3x 5x 5
690:2x 3x 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 5x 5x 23x 23 = 158700
Therefore, the value for common factors is 158700.
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 = 76956518340000/(1x158700)
LCM = 76956518340000/158700
LCM = 484918200
Thus, we can understand that the LCM of 901,920,299,450,690 is 484918200.
