Given numbers are 721,572,286,167
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,572,286,167 is 68872804.
Find LCM of 721,572,286,167 with Prime Factorization
2 | 721, 572, 286, 167 |
11 | 721, 286, 143, 167 |
13 | 721, 26, 13, 167 |
721, 2, 1, 167 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 13 x 721 x 2 x 1 x 167 = 68872804
Therefore, the lowest common multiple of 721,572,286,167 is 68872804.
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.
721 x 572 x 286 x 167 = 19697621944
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.
721 : 1, 7, 103, 721
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
286 : 1, 2, 11, 13, 22, 26, 143, 286
167 : 1, 167
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,572,286,167, is 1.
Now, the common factors can be found like this.
721:7x 103
572:2x 2x 11x 13
286:2x 11x 13
167:167
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 13 = 286
Therefore, the value for common factors is 286.
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 = 19697621944/(1x286)
LCM = 19697621944/286
LCM = 68872804
Thus, we can understand that the LCM of 721,572,286,167 is 68872804.
