Find LCM of 900,621,553,355,770 with Prime Factorization
| 2 | 900, 621, 553, 355, 770 |
| 3 | 450, 621, 553, 355, 385 |
| 3 | 150, 207, 553, 355, 385 |
| 5 | 50, 69, 553, 355, 385 |
| 7 | 10, 69, 553, 71, 77 |
| 10, 69, 79, 71, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 7 x 10 x 69 x 79 x 71 x 11 = 26820555300
Therefore, the lowest common multiple of 900,621,553,355,770 is 26820555300.
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 621 x 553 x 355 x 770 = 84484749195000
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
621 : 1, 3, 9, 23, 27, 69, 207, 621
553 : 1, 7, 79, 553
355 : 1, 5, 71, 355
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 900,621,553,355,770, is 1.
Now, the common factors can be found like this.
900:2x 2x 3x 3x 5x 5
621:3x 3x 3x 23
553:7x 79
355:5x 71
770:2x 5x 7x 11
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 3x 5x 5x 7 = 3150
Therefore, the value for common factors is 3150.
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 = 84484749195000/(1x3150)
LCM = 84484749195000/3150
LCM = 26820555300
Thus, we can understand that the LCM of 900,621,553,355,770 is 26820555300.
