Given numbers are 805,973,637,918,129
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 805,973,637,918,129 is 401941833930.
Find LCM of 805,973,637,918,129 with Prime Factorization
3 | 805, 973, 637, 918, 129 |
7 | 805, 973, 637, 306, 43 |
115, 139, 91, 306, 43 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 115 x 139 x 91 x 306 x 43 = 401941833930
Therefore, the lowest common multiple of 805,973,637,918,129 is 401941833930.
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.
805 x 973 x 637 x 918 x 129 = 59085449587710
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.
805 : 1, 5, 7, 23, 35, 115, 161, 805
973 : 1, 7, 139, 973
637 : 1, 7, 13, 49, 91, 637
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
129 : 1, 3, 43, 129
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 805,973,637,918,129, is 1.
Now, the common factors can be found like this.
805:5x 7x 23
973:7x 139
637:7x 7x 13
918:2x 3x 3x 3x 17
129:3x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 7 = 147
Therefore, the value for common factors is 147.
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 = 59085449587710/(1x147)
LCM = 59085449587710/147
LCM = 401941833930
Thus, we can understand that the LCM of 805,973,637,918,129 is 401941833930.
