Given numbers are 974,478,656,812,936
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 974,478,656,812,936 is 1813479293808.
Find LCM of 974,478,656,812,936 with Prime Factorization
| 2 | 974, 478, 656, 812, 936 |
| 2 | 487, 239, 328, 406, 468 |
| 2 | 487, 239, 164, 203, 234 |
| 487, 239, 82, 203, 117 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 487 x 239 x 82 x 203 x 117 = 1813479293808
Therefore, the lowest common multiple of 974,478,656,812,936 is 1813479293808.
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.
974 x 478 x 656 x 812 x 936 = 232125349607424
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.
974 : 1, 2, 487, 974
478 : 1, 2, 239, 478
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
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
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 974,478,656,812,936, is 2.
Now, the common factors can be found like this.
974:2x 487
478:2x 239
656:2x 2x 2x 2x 41
812:2x 2x 7x 29
936:2x 2x 2x 3x 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 2x 2x 2 = 64
Therefore, the value for common factors is 64.
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 = 232125349607424/(2x64)
LCM = 232125349607424/128
LCM = 1813479293808
Thus, we can understand that the LCM of 974,478,656,812,936 is 1813479293808.
