Given numbers are 418,747,980,740
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 418,747,980,740 is 5661019980.
Find LCM of 418,747,980,740 with Prime Factorization
| 2 | 418, 747, 980, 740 |
| 2 | 209, 747, 490, 370 |
| 5 | 209, 747, 245, 185 |
| 209, 747, 49, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 209 x 747 x 49 x 37 = 5661019980
Therefore, the lowest common multiple of 418,747,980,740 is 5661019980.
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.
418 x 747 x 980 x 740 = 226440799200
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.
418 : 1, 2, 11, 19, 22, 38, 209, 418
747 : 1, 3, 9, 83, 249, 747
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,747,980,740, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
747:3x 3x 83
980:2x 2x 5x 7x 7
740:2x 2x 5x 37
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 5 = 40
Therefore, the value for common factors is 40.
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 = 226440799200/(1x40)
LCM = 226440799200/40
LCM = 5661019980
Thus, we can understand that the LCM of 418,747,980,740 is 5661019980.
