Given numbers are 100,628,970,638,849
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 100,628,970,638,849 is 412448529900.
Find LCM of 100,628,970,638,849 with Prime Factorization
| 2 | 100, 628, 970, 638, 849 |
| 2 | 50, 314, 485, 319, 849 |
| 5 | 25, 157, 485, 319, 849 |
| 5, 157, 97, 319, 849 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 5 x 157 x 97 x 319 x 849 = 412448529900
Therefore, the lowest common multiple of 100,628,970,638,849 is 412448529900.
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.
100 x 628 x 970 x 638 x 849 = 32995882392000
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.
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
628 : 1, 2, 4, 157, 314, 628
970 : 1, 2, 5, 10, 97, 194, 485, 970
638 : 1, 2, 11, 22, 29, 58, 319, 638
849 : 1, 3, 283, 849
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 100,628,970,638,849, is 1.
Now, the common factors can be found like this.
100:2x 2x 5x 5
628:2x 2x 157
970:2x 5x 97
638:2x 11x 29
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 2x 2x 2x 5 = 80
Therefore, the value for common factors is 80.
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 = 32995882392000/(1x80)
LCM = 32995882392000/80
LCM = 412448529900
Thus, we can understand that the LCM of 100,628,970,638,849 is 412448529900.
