Given numbers are 707,978,428,312
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 707,978,428,312 is 3847205544.
Find LCM of 707,978,428,312 with Prime Factorization
| 2 | 707, 978, 428, 312 |
| 2 | 707, 489, 214, 156 |
| 3 | 707, 489, 107, 78 |
| 707, 163, 107, 26 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 707 x 163 x 107 x 26 = 3847205544
Therefore, the lowest common multiple of 707,978,428,312 is 3847205544.
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.
707 x 978 x 428 x 312 = 92332933056
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.
707 : 1, 7, 101, 707
978 : 1, 2, 3, 6, 163, 326, 489, 978
428 : 1, 2, 4, 107, 214, 428
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 707,978,428,312, is 1.
Now, the common factors can be found like this.
707:7x 101
978:2x 3x 163
428:2x 2x 107
312:2x 2x 2x 3x 13
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 3 = 24
Therefore, the value for common factors is 24.
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 = 92332933056/(1x24)
LCM = 92332933056/24
LCM = 3847205544
Thus, we can understand that the LCM of 707,978,428,312 is 3847205544.
