Given numbers are 202,786,983,390,615
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 202,786,983,390,615 is 207967107270.
Find LCM of 202,786,983,390,615 with Prime Factorization
| 2 | 202, 786, 983, 390, 615 |
| 3 | 101, 393, 983, 195, 615 |
| 5 | 101, 131, 983, 65, 205 |
| 101, 131, 983, 13, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 101 x 131 x 983 x 13 x 41 = 207967107270
Therefore, the lowest common multiple of 202,786,983,390,615 is 207967107270.
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.
202 x 786 x 983 x 390 x 615 = 37434079308600
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.
202 : 1, 2, 101, 202
786 : 1, 2, 3, 6, 131, 262, 393, 786
983 : 1, 983
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
615 : 1, 3, 5, 15, 41, 123, 205, 615
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 202,786,983,390,615, is 1.
Now, the common factors can be found like this.
202:2x 101
786:2x 3x 131
983:983
390:2x 3x 5x 13
615:3x 5x 41
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 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 37434079308600/(1x180)
LCM = 37434079308600/180
LCM = 207967107270
Thus, we can understand that the LCM of 202,786,983,390,615 is 207967107270.
