Given numbers are 978,931,532
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 978,931,532 is 1821036.
Find LCM of 978,931,532 with Prime Factorization
| 2 | 978, 931, 532 |
| 7 | 489, 931, 266 |
| 19 | 489, 133, 38 |
| 489, 7, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 19 x 489 x 7 x 2 = 1821036
Therefore, the lowest common multiple of 978,931,532 is 1821036.
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 931 x 532 = 484395576
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
931 : 1, 7, 19, 49, 133, 931
532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,931,532, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
931:7x 7x 19
532:2x 2x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 19 = 266
Therefore, the value for common factors is 266.
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 = 484395576/(1x266)
LCM = 484395576/266
LCM = 1821036
Thus, we can understand that the LCM of 978,931,532 is 1821036.
