Given numbers are 812,669,172,806,761
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 812,669,172,806,761 is 7163748087132.
Find LCM of 812,669,172,806,761 with Prime Factorization
2 | 812, 669, 172, 806, 761 |
2 | 406, 669, 86, 403, 761 |
203, 669, 43, 403, 761 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 203 x 669 x 43 x 403 x 761 = 7163748087132
Therefore, the lowest common multiple of 812,669,172,806,761 is 7163748087132.
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 669 x 172 x 806 x 761 = 57309984697056
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
669 : 1, 3, 223, 669
172 : 1, 2, 4, 43, 86, 172
806 : 1, 2, 13, 26, 31, 62, 403, 806
761 : 1, 761
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,669,172,806,761, is 1.
Now, the common factors can be found like this.
812:2x 2x 7x 29
669:3x 223
172:2x 2x 43
806:2x 13x 31
761:761
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 2 = 8
Therefore, the value for common factors is 8.
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 = 57309984697056/(1x8)
LCM = 57309984697056/8
LCM = 7163748087132
Thus, we can understand that the LCM of 812,669,172,806,761 is 7163748087132.
