Given numbers are 812,987,931,938,539
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 812,987,931,938,539 is 11222620332.
Find LCM of 812,987,931,938,539 with Prime Factorization
| 2 | 812, 987, 931, 938, 539 |
| 7 | 406, 987, 931, 469, 539 |
| 7 | 58, 141, 133, 67, 77 |
| 58, 141, 19, 67, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 7 x 58 x 141 x 19 x 67 x 11 = 11222620332
Therefore, the lowest common multiple of 812,987,931,938,539 is 11222620332.
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.
812 x 987 x 931 x 938 x 539 = 377237159839848
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.
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
987 : 1, 3, 7, 21, 47, 141, 329, 987
931 : 1, 7, 19, 49, 133, 931
938 : 1, 2, 7, 14, 67, 134, 469, 938
539 : 1, 7, 11, 49, 77, 539
7 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,987,931,938,539, is 7.
Now, the common factors can be found like this.
812:2x 2x 7x 29
987:3x 7x 47
931:7x 7x 19
938:2x 7x 67
539:7x 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 7x 7x 7x 7 = 4802
Therefore, the value for common factors is 4802.
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 = 377237159839848/(7x4802)
LCM = 377237159839848/33614
LCM = 11222620332
Thus, we can understand that the LCM of 812,987,931,938,539 is 11222620332.
