Given numbers are 978,748,926,748
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 978,748,926,748 is 169352436.
Find LCM of 978,748,926,748 with Prime Factorization
| 2 | 978, 748, 926, 748 |
| 2 | 489, 374, 463, 374 |
| 11 | 489, 187, 463, 187 |
| 17 | 489, 17, 463, 17 |
| 489, 1, 463, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 17 x 489 x 1 x 463 x 1 = 169352436
Therefore, the lowest common multiple of 978,748,926,748 is 169352436.
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.
978 x 748 x 926 x 748 = 506702488512
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.
978 : 1, 2, 3, 6, 163, 326, 489, 978
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
926 : 1, 2, 463, 926
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,748,926,748, is 2.
Now, the common factors can be found like this.
978:2x 3x 163
748:2x 2x 11x 17
926:2x 463
748:2x 2x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 11x 17 = 1496
Therefore, the value for common factors is 1496.
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 = 506702488512/(2x1496)
LCM = 506702488512/2992
LCM = 169352436
Thus, we can understand that the LCM of 978,748,926,748 is 169352436.
