Given numbers are 757,849,428,936,978
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 757,849,428,936,978 is 3497273087256.
Find LCM of 757,849,428,936,978 with Prime Factorization
| 2 | 757, 849, 428, 936, 978 |
| 2 | 757, 849, 214, 468, 489 |
| 3 | 757, 849, 107, 234, 489 |
| 757, 283, 107, 78, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 757 x 283 x 107 x 78 x 163 = 3497273087256
Therefore, the lowest common multiple of 757,849,428,936,978 is 3497273087256.
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.
757 x 849 x 428 x 936 x 978 = 251803662282432
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.
757 : 1, 757
849 : 1, 3, 283, 849
428 : 1, 2, 4, 107, 214, 428
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
978 : 1, 2, 3, 6, 163, 326, 489, 978
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 757,849,428,936,978, is 1.
Now, the common factors can be found like this.
757:757
849:3x 283
428:2x 2x 107
936:2x 2x 2x 3x 3x 13
978:2x 3x 163
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 3x 3 = 72
Therefore, the value for common factors is 72.
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 = 251803662282432/(1x72)
LCM = 251803662282432/72
LCM = 3497273087256
Thus, we can understand that the LCM of 757,849,428,936,978 is 3497273087256.
