Given numbers are 426,402,323,547,978
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 426,402,323,547,978 is 821981143626.
Find LCM of 426,402,323,547,978 with Prime Factorization
| 2 | 426, 402, 323, 547, 978 |
| 3 | 213, 201, 323, 547, 489 |
| 71, 67, 323, 547, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 71 x 67 x 323 x 547 x 163 = 821981143626
Therefore, the lowest common multiple of 426,402,323,547,978 is 821981143626.
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.
426 x 402 x 323 x 547 x 978 = 29591321170536
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.
426 : 1, 2, 3, 6, 71, 142, 213, 426
402 : 1, 2, 3, 6, 67, 134, 201, 402
323 : 1, 17, 19, 323
547 : 1, 547
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 426,402,323,547,978, is 1.
Now, the common factors can be found like this.
426:2x 3x 71
402:2x 3x 67
323:17x 19
547:547
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 3x 3 = 36
Therefore, the value for common factors is 36.
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 = 29591321170536/(1x36)
LCM = 29591321170536/36
LCM = 821981143626
Thus, we can understand that the LCM of 426,402,323,547,978 is 821981143626.
