Given numbers are 202,391,561,951
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 202,391,561,951 is 826230702.
Find LCM of 202,391,561,951 with Prime Factorization
| 3 | 202, 391, 561, 951 |
| 17 | 202, 391, 187, 317 |
| 202, 23, 11, 317 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 202 x 23 x 11 x 317 = 826230702
Therefore, the lowest common multiple of 202,391,561,951 is 826230702.
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 391 x 561 x 951 = 42137765802
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
391 : 1, 17, 23, 391
561 : 1, 3, 11, 17, 33, 51, 187, 561
951 : 1, 3, 317, 951
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 202,391,561,951, is 1.
Now, the common factors can be found like this.
202:2x 101
391:17x 23
561:3x 11x 17
951:3x 317
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 17 = 51
Therefore, the value for common factors is 51.
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 = 42137765802/(1x51)
LCM = 42137765802/51
LCM = 826230702
Thus, we can understand that the LCM of 202,391,561,951 is 826230702.
