Given numbers are 564,639,638,145
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 564,639,638,145 is 191610540.
Find LCM of 564,639,638,145 with Prime Factorization
| 2 | 564, 639, 638, 145 |
| 3 | 282, 639, 319, 145 |
| 29 | 94, 213, 319, 145 |
| 94, 213, 11, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 29 x 94 x 213 x 11 x 5 = 191610540
Therefore, the lowest common multiple of 564,639,638,145 is 191610540.
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.
564 x 639 x 638 x 145 = 33340233960
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.
564 : 1, 2, 3, 4, 6, 12, 47, 94, 141, 188, 282, 564
639 : 1, 3, 9, 71, 213, 639
638 : 1, 2, 11, 22, 29, 58, 319, 638
145 : 1, 5, 29, 145
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 564,639,638,145, is 1.
Now, the common factors can be found like this.
564:2x 2x 3x 47
639:3x 3x 71
638:2x 11x 29
145:5x 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 3x 29 = 174
Therefore, the value for common factors is 174.
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 = 33340233960/(1x174)
LCM = 33340233960/174
LCM = 191610540
Thus, we can understand that the LCM of 564,639,638,145 is 191610540.
