Given numbers are 619,791,678,568
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 619,791,678,568 is 834327816.
Find LCM of 619,791,678,568 with Prime Factorization
| 2 | 619, 791, 678, 568 |
| 113 | 619, 791, 339, 284 |
| 619, 7, 3, 284 |
Multiply the prime numbers at the bottom and the left side.
2 x 113 x 619 x 7 x 3 x 284 = 834327816
Therefore, the lowest common multiple of 619,791,678,568 is 834327816.
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.
619 x 791 x 678 x 568 = 188558086416
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.
619 : 1, 619
791 : 1, 7, 113, 791
678 : 1, 2, 3, 6, 113, 226, 339, 678
568 : 1, 2, 4, 8, 71, 142, 284, 568
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 619,791,678,568, is 1.
Now, the common factors can be found like this.
619:619
791:7x 113
678:2x 3x 113
568:2x 2x 2x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 113 = 226
Therefore, the value for common factors is 226.
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 = 188558086416/(1x226)
LCM = 188558086416/226
LCM = 834327816
Thus, we can understand that the LCM of 619,791,678,568 is 834327816.
