Given numbers are 189,821,453,119,994
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 189,821,453,119,994 is 56561272866.
Find LCM of 189,821,453,119,994 with Prime Factorization
| 3 | 189, 821, 453, 119, 994 |
| 7 | 63, 821, 151, 119, 994 |
| 9, 821, 151, 17, 142 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 9 x 821 x 151 x 17 x 142 = 56561272866
Therefore, the lowest common multiple of 189,821,453,119,994 is 56561272866.
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.
189 x 821 x 453 x 119 x 994 = 8314507111302
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.
189 : 1, 3, 7, 9, 21, 27, 63, 189
821 : 1, 821
453 : 1, 3, 151, 453
119 : 1, 7, 17, 119
994 : 1, 2, 7, 14, 71, 142, 497, 994
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,821,453,119,994, is 1.
Now, the common factors can be found like this.
189:3x 3x 3x 7
821:821
453:3x 151
119:7x 17
994:2x 7x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 7 = 147
Therefore, the value for common factors is 147.
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 = 8314507111302/(1x147)
LCM = 8314507111302/147
LCM = 56561272866
Thus, we can understand that the LCM of 189,821,453,119,994 is 56561272866.
