Given numbers are 785,850,434,616
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 785,850,434,616 is 1274180600.
Find LCM of 785,850,434,616 with Prime Factorization
| 2 | 785, 850, 434, 616 |
| 5 | 785, 425, 217, 308 |
| 7 | 157, 85, 217, 308 |
| 157, 85, 31, 44 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 157 x 85 x 31 x 44 = 1274180600
Therefore, the lowest common multiple of 785,850,434,616 is 1274180600.
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.
785 x 850 x 434 x 616 = 178385284000
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.
785 : 1, 5, 157, 785
850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850
434 : 1, 2, 7, 14, 31, 62, 217, 434
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,850,434,616, is 1.
Now, the common factors can be found like this.
785:5x 157
850:2x 5x 5x 17
434:2x 7x 31
616:2x 2x 2x 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 2x 5x 7 = 140
Therefore, the value for common factors is 140.
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 = 178385284000/(1x140)
LCM = 178385284000/140
LCM = 1274180600
Thus, we can understand that the LCM of 785,850,434,616 is 1274180600.
