Given numbers are 639,100,186,692,580
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,100,186,692,580 is 9938175300.
Find LCM of 639,100,186,692,580 with Prime Factorization
| 2 | 639, 100, 186, 692, 580 |
| 2 | 639, 50, 93, 346, 290 |
| 3 | 639, 25, 93, 173, 145 |
| 5 | 213, 25, 31, 173, 145 |
| 213, 5, 31, 173, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 213 x 5 x 31 x 173 x 29 = 9938175300
Therefore, the lowest common multiple of 639,100,186,692,580 is 9938175300.
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.
639 x 100 x 186 x 692 x 580 = 4770324144000
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.
639 : 1, 3, 9, 71, 213, 639
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
186 : 1, 2, 3, 6, 31, 62, 93, 186
692 : 1, 2, 4, 173, 346, 692
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,100,186,692,580, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
100:2x 2x 5x 5
186:2x 3x 31
692:2x 2x 173
580:2x 2x 5x 29
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 2x 2x 2x 3x 5 = 480
Therefore, the value for common factors is 480.
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 = 4770324144000/(1x480)
LCM = 4770324144000/480
LCM = 9938175300
Thus, we can understand that the LCM of 639,100,186,692,580 is 9938175300.
