Find LCM of 300,625,679,420,785 with Prime Factorization
| 2 | 300, 625, 679, 420, 785 |
| 2 | 150, 625, 679, 210, 785 |
| 3 | 75, 625, 679, 105, 785 |
| 5 | 25, 625, 679, 35, 785 |
| 5 | 5, 125, 679, 7, 157 |
| 7 | 1, 25, 679, 7, 157 |
| 1, 25, 97, 1, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 5 x 7 x 1 x 25 x 97 x 1 x 157 = 799522500
Therefore, the lowest common multiple of 300,625,679,420,785 is 799522500.
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.
300 x 625 x 679 x 420 x 785 = 41974931250000
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.
300 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300
625 : 1, 5, 25, 125, 625
679 : 1, 7, 97, 679
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
785 : 1, 5, 157, 785
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 300,625,679,420,785, is 1.
Now, the common factors can be found like this.
300:2x 2x 3x 5x 5
625:5x 5x 5x 5
679:7x 97
420:2x 2x 3x 5x 7
785:5x 157
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 5x 5x 7 = 52500
Therefore, the value for common factors is 52500.
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 = 41974931250000/(1x52500)
LCM = 41974931250000/52500
LCM = 799522500
Thus, we can understand that the LCM of 300,625,679,420,785 is 799522500.
