Given numbers are 607,981,545,940,478
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 607,981,545,940,478 is 133777616220.
Find LCM of 607,981,545,940,478 with Prime Factorization
| 2 | 607, 981, 545, 940, 478 |
| 5 | 607, 981, 545, 470, 239 |
| 109 | 607, 981, 109, 94, 239 |
| 607, 9, 1, 94, 239 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 109 x 607 x 9 x 1 x 94 x 239 = 133777616220
Therefore, the lowest common multiple of 607,981,545,940,478 is 133777616220.
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.
607 x 981 x 545 x 940 x 478 = 145817601679800
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.
607 : 1, 607
981 : 1, 3, 9, 109, 327, 981
545 : 1, 5, 109, 545
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
478 : 1, 2, 239, 478
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 607,981,545,940,478, is 1.
Now, the common factors can be found like this.
607:607
981:3x 3x 109
545:5x 109
940:2x 2x 5x 47
478:2x 239
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 109 = 1090
Therefore, the value for common factors is 1090.
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 = 145817601679800/(1x1090)
LCM = 145817601679800/1090
LCM = 133777616220
Thus, we can understand that the LCM of 607,981,545,940,478 is 133777616220.
