Given numbers are 670,381,923,664
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 670,381,923,664 is 78223917720.
Find LCM of 670,381,923,664 with Prime Factorization
2 | 670, 381, 923, 664 |
335, 381, 923, 332 |
Multiply the prime numbers at the bottom and the left side.
2 x 335 x 381 x 923 x 332 = 78223917720
Therefore, the lowest common multiple of 670,381,923,664 is 78223917720.
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.
670 x 381 x 923 x 664 = 156447835440
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.
670 : 1, 2, 5, 10, 67, 134, 335, 670
381 : 1, 3, 127, 381
923 : 1, 13, 71, 923
664 : 1, 2, 4, 8, 83, 166, 332, 664
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 670,381,923,664, is 1.
Now, the common factors can be found like this.
670:2x 5x 67
381:3x 127
923:13x 71
664:2x 2x 2x 83
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 = 156447835440/(1x2)
LCM = 156447835440/2
LCM = 78223917720
Thus, we can understand that the LCM of 670,381,923,664 is 78223917720.
