Given numbers are 621,781,904,671
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 621,781,904,671 is 26744895144.
Find LCM of 621,781,904,671 with Prime Factorization
11 | 621, 781, 904, 671 |
621, 71, 904, 61 |
Multiply the prime numbers at the bottom and the left side.
11 x 621 x 71 x 904 x 61 = 26744895144
Therefore, the lowest common multiple of 621,781,904,671 is 26744895144.
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.
621 x 781 x 904 x 671 = 294193846584
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.
621 : 1, 3, 9, 23, 27, 69, 207, 621
781 : 1, 11, 71, 781
904 : 1, 2, 4, 8, 113, 226, 452, 904
671 : 1, 11, 61, 671
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,781,904,671, is 1.
Now, the common factors can be found like this.
621:3x 3x 3x 23
781:11x 71
904:2x 2x 2x 113
671:11x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 294193846584/(1x11)
LCM = 294193846584/11
LCM = 26744895144
Thus, we can understand that the LCM of 621,781,904,671 is 26744895144.
