Given numbers are 994,841,638,748,761
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 994,841,638,748,761 is 237924211756.
Find LCM of 994,841,638,748,761 with Prime Factorization
| 2 | 994, 841, 638, 748, 761 |
| 11 | 497, 841, 319, 374, 761 |
| 29 | 497, 841, 29, 34, 761 |
| 497, 1, 29, 34, 761 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 29 x 497 x 1 x 29 x 34 x 761 = 237924211756
Therefore, the lowest common multiple of 994,841,638,748,761 is 237924211756.
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.
994 x 841 x 638 x 748 x 761 = 303591294200656
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.
994 : 1, 2, 7, 14, 71, 142, 497, 994
841 : 1, 29, 841
638 : 1, 2, 11, 22, 29, 58, 319, 638
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
761 : 1, 761
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 994,841,638,748,761, is 1.
Now, the common factors can be found like this.
994:2x 7x 71
841:29x 29
638:2x 11x 29
748:2x 2x 11x 17
761:761
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 11x 29 = 1276
Therefore, the value for common factors is 1276.
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 = 303591294200656/(1x1276)
LCM = 303591294200656/1276
LCM = 237924211756
Thus, we can understand that the LCM of 994,841,638,748,761 is 237924211756.
