Given numbers are 649,722,428
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 649,722,428 is 100275692.
Find LCM of 649,722,428 with Prime Factorization
| 2 | 649, 722, 428 |
| 649, 361, 214 |
Multiply the prime numbers at the bottom and the left side.
2 x 649 x 361 x 214 = 100275692
Therefore, the lowest common multiple of 649,722,428 is 100275692.
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.
649 x 722 x 428 = 200551384
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.
649 : 1, 11, 59, 649
722 : 1, 2, 19, 38, 361, 722
428 : 1, 2, 4, 107, 214, 428
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,722,428, is 1.
Now, the common factors can be found like this.
649:11x 59
722:2x 19x 19
428:2x 2x 107
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 = 200551384/(1x2)
LCM = 200551384/2
LCM = 100275692
Thus, we can understand that the LCM of 649,722,428 is 100275692.
