Given numbers are 865,956,694,924,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 865,956,694,924,638 is 1922265857820.
Find LCM of 865,956,694,924,638 with Prime Factorization
| 2 | 865, 956, 694, 924, 638 |
| 2 | 865, 478, 347, 462, 319 |
| 11 | 865, 239, 347, 231, 319 |
| 865, 239, 347, 21, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 865 x 239 x 347 x 21 x 29 = 1922265857820
Therefore, the lowest common multiple of 865,956,694,924,638 is 1922265857820.
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.
865 x 956 x 694 x 924 x 638 = 338318790976320
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.
865 : 1, 5, 173, 865
956 : 1, 2, 4, 239, 478, 956
694 : 1, 2, 347, 694
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 865,956,694,924,638, is 1.
Now, the common factors can be found like this.
865:5x 173
956:2x 2x 239
694:2x 347
924:2x 2x 3x 7x 11
638:2x 11x 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 2x 2x 11 = 176
Therefore, the value for common factors is 176.
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 = 338318790976320/(1x176)
LCM = 338318790976320/176
LCM = 1922265857820
Thus, we can understand that the LCM of 865,956,694,924,638 is 1922265857820.
