Given numbers are 391,974,370,437,986
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,974,370,437,986 is 38820313790.
Find LCM of 391,974,370,437,986 with Prime Factorization
2 | 391, 974, 370, 437, 986 |
17 | 391, 487, 185, 437, 493 |
23 | 23, 487, 185, 437, 29 |
1, 487, 185, 19, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 23 x 1 x 487 x 185 x 19 x 29 = 38820313790
Therefore, the lowest common multiple of 391,974,370,437,986 is 38820313790.
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.
391 x 974 x 370 x 437 x 986 = 60714970767560
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.
391 : 1, 17, 23, 391
974 : 1, 2, 487, 974
370 : 1, 2, 5, 10, 37, 74, 185, 370
437 : 1, 19, 23, 437
986 : 1, 2, 17, 29, 34, 58, 493, 986
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,974,370,437,986, is 1.
Now, the common factors can be found like this.
391:17x 23
974:2x 487
370:2x 5x 37
437:19x 23
986:2x 17x 29
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 17x 23 = 1564
Therefore, the value for common factors is 1564.
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 = 60714970767560/(1x1564)
LCM = 60714970767560/1564
LCM = 38820313790
Thus, we can understand that the LCM of 391,974,370,437,986 is 38820313790.
