Given numbers are 478,425,420,697,849
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 478,425,420,697,849 is 99000276900.
Find LCM of 478,425,420,697,849 with Prime Factorization
| 2 | 478, 425, 420, 697, 849 |
| 3 | 239, 425, 210, 697, 849 |
| 5 | 239, 425, 70, 697, 283 |
| 17 | 239, 85, 14, 697, 283 |
| 239, 5, 14, 41, 283 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 17 x 239 x 5 x 14 x 41 x 283 = 99000276900
Therefore, the lowest common multiple of 478,425,420,697,849 is 99000276900.
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 425 x 420 x 697 x 849 = 50490141219000
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
425 : 1, 5, 17, 25, 85, 425
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
697 : 1, 17, 41, 697
849 : 1, 3, 283, 849
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,425,420,697,849, is 1.
Now, the common factors can be found like this.
478:2x 239
425:5x 5x 17
420:2x 2x 3x 5x 7
697:17x 41
849:3x 283
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 17 = 510
Therefore, the value for common factors is 510.
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 = 50490141219000/(1x510)
LCM = 50490141219000/510
LCM = 99000276900
Thus, we can understand that the LCM of 478,425,420,697,849 is 99000276900.
