Given numbers are 647,748,926,557
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 647,748,926,557 is 124807896796.
Find LCM of 647,748,926,557 with Prime Factorization
| 2 | 647, 748, 926, 557 |
| 647, 374, 463, 557 |
Multiply the prime numbers at the bottom and the left side.
2 x 647 x 374 x 463 x 557 = 124807896796
Therefore, the lowest common multiple of 647,748,926,557 is 124807896796.
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.
647 x 748 x 926 x 557 = 249615793592
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.
647 : 1, 647
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
926 : 1, 2, 463, 926
557 : 1, 557
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,748,926,557, is 1.
Now, the common factors can be found like this.
647:647
748:2x 2x 11x 17
926:2x 463
557:557
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 = 249615793592/(1x2)
LCM = 249615793592/2
LCM = 124807896796
Thus, we can understand that the LCM of 647,748,926,557 is 124807896796.
