Given numbers are 478,688,392,277,998
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 478,688,392,277,998 is 1113685932464.
Find LCM of 478,688,392,277,998 with Prime Factorization
| 2 | 478, 688, 392, 277, 998 |
| 2 | 239, 344, 196, 277, 499 |
| 2 | 239, 172, 98, 277, 499 |
| 239, 86, 49, 277, 499 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 239 x 86 x 49 x 277 x 499 = 1113685932464
Therefore, the lowest common multiple of 478,688,392,277,998 is 1113685932464.
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.
478 x 688 x 392 x 277 x 998 = 35637949838848
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.
478 : 1, 2, 239, 478
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
277 : 1, 277
998 : 1, 2, 499, 998
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,688,392,277,998, is 1.
Now, the common factors can be found like this.
478:2x 239
688:2x 2x 2x 2x 43
392:2x 2x 2x 7x 7
277:277
998:2x 499
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 2 = 32
Therefore, the value for common factors is 32.
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 = 35637949838848/(1x32)
LCM = 35637949838848/32
LCM = 1113685932464
Thus, we can understand that the LCM of 478,688,392,277,998 is 1113685932464.
