Given numbers are 869,688,761,806
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 869,688,761,806 is 183357178576.
Find LCM of 869,688,761,806 with Prime Factorization
| 2 | 869, 688, 761, 806 |
| 869, 344, 761, 403 |
Multiply the prime numbers at the bottom and the left side.
2 x 869 x 344 x 761 x 403 = 183357178576
Therefore, the lowest common multiple of 869,688,761,806 is 183357178576.
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.
869 x 688 x 761 x 806 = 366714357152
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.
869 : 1, 11, 79, 869
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
761 : 1, 761
806 : 1, 2, 13, 26, 31, 62, 403, 806
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 869,688,761,806, is 1.
Now, the common factors can be found like this.
869:11x 79
688:2x 2x 2x 2x 43
761:761
806:2x 13x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 366714357152/(1x2)
LCM = 366714357152/2
LCM = 183357178576
Thus, we can understand that the LCM of 869,688,761,806 is 183357178576.
