Given numbers are 942,685,140,385
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 942,685,140,385 is 99371580.
Find LCM of 942,685,140,385 with Prime Factorization
| 2 | 942, 685, 140, 385 |
| 5 | 471, 685, 70, 385 |
| 7 | 471, 137, 14, 77 |
| 471, 137, 2, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 471 x 137 x 2 x 11 = 99371580
Therefore, the lowest common multiple of 942,685,140,385 is 99371580.
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.
942 x 685 x 140 x 385 = 34780053000
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.
942 : 1, 2, 3, 6, 157, 314, 471, 942
685 : 1, 5, 137, 685
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
385 : 1, 5, 7, 11, 35, 55, 77, 385
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 942,685,140,385, is 1.
Now, the common factors can be found like this.
942:2x 3x 157
685:5x 137
140:2x 2x 5x 7
385:5x 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 5x 5x 7 = 350
Therefore, the value for common factors is 350.
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 = 34780053000/(1x350)
LCM = 34780053000/350
LCM = 99371580
Thus, we can understand that the LCM of 942,685,140,385 is 99371580.
