Given numbers are 850,772,350,390
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 850,772,350,390 is 89571300.
Find LCM of 850,772,350,390 with Prime Factorization
| 2 | 850, 772, 350, 390 |
| 5 | 425, 386, 175, 195 |
| 5 | 85, 386, 35, 39 |
| 17, 386, 7, 39 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 5 x 17 x 386 x 7 x 39 = 89571300
Therefore, the lowest common multiple of 850,772,350,390 is 89571300.
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.
850 x 772 x 350 x 390 = 89571300000
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.
850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850
772 : 1, 2, 4, 193, 386, 772
350 : 1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175, 350
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 850,772,350,390, is 2.
Now, the common factors can be found like this.
850:2x 5x 5x 17
772:2x 2x 193
350:2x 5x 5x 7
390:2x 3x 5x 13
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 5x 5x 5 = 500
Therefore, the value for common factors is 500.
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 = 89571300000/(2x500)
LCM = 89571300000/1000
LCM = 89571300
Thus, we can understand that the LCM of 850,772,350,390 is 89571300.
