Given numbers are 638,487,754,188,626
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 638,487,754,188,626 is 118840695116.
Find LCM of 638,487,754,188,626 with Prime Factorization
| 2 | 638, 487, 754, 188, 626 |
| 29 | 319, 487, 377, 94, 313 |
| 11, 487, 13, 94, 313 |
Multiply the prime numbers at the bottom and the left side.
2 x 29 x 11 x 487 x 13 x 94 x 313 = 118840695116
Therefore, the lowest common multiple of 638,487,754,188,626 is 118840695116.
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.
638 x 487 x 754 x 188 x 626 = 27571041266912
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.
638 : 1, 2, 11, 22, 29, 58, 319, 638
487 : 1, 487
754 : 1, 2, 13, 26, 29, 58, 377, 754
188 : 1, 2, 4, 47, 94, 188
626 : 1, 2, 313, 626
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,487,754,188,626, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
487:487
754:2x 13x 29
188:2x 2x 47
626:2x 313
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 29 = 232
Therefore, the value for common factors is 232.
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 = 27571041266912/(1x232)
LCM = 27571041266912/232
LCM = 118840695116
Thus, we can understand that the LCM of 638,487,754,188,626 is 118840695116.
