Given numbers are 733,389,763,686
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 733,389,763,686 is 21320834038.
Find LCM of 733,389,763,686 with Prime Factorization
| 7 | 733, 389, 763, 686 |
| 733, 389, 109, 98 |
Multiply the prime numbers at the bottom and the left side.
7 x 733 x 389 x 109 x 98 = 21320834038
Therefore, the lowest common multiple of 733,389,763,686 is 21320834038.
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.
733 x 389 x 763 x 686 = 149245838266
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.
733 : 1, 733
389 : 1, 389
763 : 1, 7, 109, 763
686 : 1, 2, 7, 14, 49, 98, 343, 686
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 733,389,763,686, is 1.
Now, the common factors can be found like this.
733:733
389:389
763:7x 109
686:2x 7x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7 = 7
Therefore, the value for common factors is 7.
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 = 149245838266/(1x7)
LCM = 149245838266/7
LCM = 21320834038
Thus, we can understand that the LCM of 733,389,763,686 is 21320834038.
